TITLEt Negative Photodiode Effect in the PrebreakdownRegion of Germaluium pn-Junctions PERIODICAL: Izvestiya Akademii nauk Uzbekskoy SSR, Seriya fiziko- matematicheskikh nauk# 1960p~No.2, PP-84-86 TEXTs The negative photodiode effect consists in the."dimin.ution of -the b iwk current for a lighting of the crystal. During the switching in of,thejight there appears a sudden enlargement of the current intensity, whereafter it becomes slowly weaker and reaches a value smaller than the-value meabured'in the darkness. If now the light is switched in again, then there appears a sudden decrease and a 'following slow increase of the current intensity. For the first time V.I.Murygin (Ref-5) has observed this effect at selenium cells. The authors investigate the same effect at specially produced germanium diodes D 7 where the crystal surface was not varnished and,whiah vere radiat9d with gamma rays of C060. Beside of the above mentioned prop'erties of the; effep,t t~-e authors proved a temperature dependence.,The authors try to Card 1/2 Negative Photodiode Effect in the S/166/60/600/02/10/63 Prebreakdown Region of Germanium pn-Junctions explain the effect, but the sudden variation of the current:intensity, is.not explained.

With di 'fferdnt methods the authors measure the reflection coefficients of germaniumo silicon and a germanium-silicon alloy. In the case.of silicon the measure ments are carried~out for different treatm ents of the* surface (polished, out, etched). In general*the re'flection coefficient at first decreases with an increasing wave length and then it becomes constant as far as in the infrared domain. A monotone dependence of the coefficient on the conductivity could not be observed. The treatment,of 'the surface cha~nges the coefficient. by ca. 2e.. A qualitative foundation of the observed appearances is not given. There are 4 references, 2 of which are Soviet, and 2:American.

By etching of the,surface of the germaiAum. or oilicon there appears a thin oxide film while in the preceling layer there is either an electron diminution or an otlar6;ement of the holes. With regard to these phenomena the authors propoee methods for the measurement of the capacity of a seiniconductor-electralyte- system. As an equivalent scheme the authors reoommend a combination of paralleled BC-chaina.

TITLES Reflection coefficient of visible light reflected from germanium SOURCES Nekotoriye voprosy prikladnoy fiziki, 1961, 51 - 54 TEXTS The light reflection coefficient R is more dependent on the state of the surface than is the rest of physical parameters.: Since R and the absorption coefficient depend on the energy structure of the crystal surfacev ffieasuring these coefficients permits to.infer the energy strue- ture of the germanium surface. Chemical polish of~'germanium results in the formation of an oxide coating on the crystal surface., R is not changed by etching crystals with different crystallographic directions. However, the same etching agent lays bare quite definite faces, independ- ent of the orientation of the crystal. This means~that either the ratio of the area of faces remains unaltered, or R is not dependent on the type of crystallographic faces. To decide for one or the other possibility, Ro was measured for germanium treated with etching agents of this type. Card 1/3 30146 8/6 06/61/000/000/003/007 Reflection coefficient of... B1410102 Measurements showed that differently worked crystals furnished values for R differing by 20 - 3(YA. This implies that R is not dependent on the; type of crystallographic faces but on the composition and structure of the 10 - 50 f thick oxide coating. Some etching agents cause R to be changed when the crystal is rotated around an axis perpendicular to the surface investigated, passing through a number of maxima and minima. If the crystals are worked with other etching agents, R is,Jndependent of the orientation of the crystal. In this case, the correct value of R is obtained. Differences in the values of Rp occurring as a result of treating the crystal with the same etching agent, are related to the structure of the monoxide film which is gradually converted into ' dioxide in the atmosphere. Irradiated with shortwave light, this film generates an anomalously high negative photocurrent in the diodes due to the short- wave light being absorbed by the film. Gamma irradiation of germanium in moist atmosphere reduces the value of R. Ipparently, irradiation,of the germanium surface causes the formation of a film resembling the monoxide film. Indicative of this is the existence of the anomalously high negative photocurrent. Gamma irradiation of germanium,'protected from moisture, has no effect on R.

TITLEs Effect of gamma rays on germanium diodes SOURCE3 Nekotoriye voprosy prikladnoy fiziki, ~1961, .55 57 TEXTs Gamma irradiation causes a negative photoeffect in germanium diodes. The authors discovered this effect In A-7 (D-7),diodes, and reported on it earlier (Izv. AN UzSSR, ser. fiz. mat. nauk, 1960, no. 2). They assumed that this effect is due to inhomogeneities in the volume (Frenkell defects). The negative photocurront depends on the temperature and the spectral distribution of light. It increases with increasing frequency of the illuminating light. In the photocells examined, the in- crease in photocurrent was particularly striking atlozo.61b. For waves ty longer than 0 '8~,) the negative photocurrent is praotically vanishing. This means that it is due to the light being absorbed by the oxide coating and not by the surface-near layer. This was confirmed by, a series of experiments. Gamma irradiation of germanium in moist atmosphere causes Card 1/3 30 119, S/608/61/000/000/004/007 Effect of gamma rays on ... DIO/B102 the formation of a film on the surface whose reflection coefficient is similar to that of monoxide-coated (etched) germanium. This results'in the occurrence of the characteristic negative ph6tocurrent. Thus, the strong change of the diode characteristics is not only, due to inhomo- geneities of the crystal lattice but also to the,conversion of the dioxide coating int6 monoxide. Since surface electrons.are transferred to the monoxide coating, it is assumed that it is negatively~charged by.applying a voltage in the blocked direction. This resultu in the formation of holes in the surface-near "layer that provide a channel forexcess con- ductivity. Light absorption transmits the electrons from the acceptor levels to the conduction band of the coating, and from theret overcoming a potential barrier, to the volume of the germanium. The oxide coating is positively charged due to accumulation of bound holes, which reduces their concentration in the channel and, subsequently, the reverse current. This"model permitted to find empirical formulas for the excess reverse current and for the photocurrent in a germanium diode. The transient characteristics of the diode were computed, experimentally verified, and graphically compared. They were found to agreq fairly well. After' applying a voltage, the reverse current increases, whereas it decreases Card 2/3 49 5/6 '0 61/000/000/004/007 B140R - Effect of gamma rays on ... 31 102 when the light is turned on.

This theory incorporates the following two assumptions: 1) the solid behaves as an isotropic continuous medium as far, as thermal vibrations area concerned and (2) all the deductions from the theory obtained for a monatomic substance automatically hold for a diatomic; lattice. The present authors point out that both these assumptions are not strictly correct.

By etching of the,surface of the germaiAum. or oilicon there appears a thin oxide film while in the preceling layer there is either an electron diminution or an otlar6;ement of the holes. With regard to these phenomena the authors propoee methods for the measurement of the capacity of a seiniconductor-electralyte- system. As an equivalent scheme the authors reoommend a combination of paralleled BC-chaina.

TITLES Reflection coefficient of visible light reflected from germanium SOURCES Nekotoriye voprosy prikladnoy fiziki, 1961, 51 - 54 TEXTS The light reflection coefficient R is more dependent on the state of the surface than is the rest of physical parameters.: Since R and the absorption coefficient depend on the energy structure of the crystal surfacev ffieasuring these coefficients permits to.infer the energy strue- ture of the germanium surface. Chemical polish of~'germanium results in the formation of an oxide coating on the crystal surface., R is not changed by etching crystals with different crystallographic directions. However, the same etching agent lays bare quite definite faces, independ- ent of the orientation of the crystal. This means~that either the ratio of the area of faces remains unaltered, or R is not dependent on the type of crystallographic faces. To decide for one or the other possibility, Ro was measured for germanium treated with etching agents of this type. Card 1/3 30146 8/6 06/61/000/000/003/007 Reflection coefficient of... B1410102 Measurements showed that differently worked crystals furnished values for R differing by 20 - 3(YA. This implies that R is not dependent on the; type of crystallographic faces but on the composition and structure of the 10 - 50 f thick oxide coating. Some etching agents cause R to be changed when the crystal is rotated around an axis perpendicular to the surface investigated, passing through a number of maxima and minima. If the crystals are worked with other etching agents, R is,Jndependent of the orientation of the crystal. In this case, the correct value of R is obtained. Differences in the values of Rp occurring as a result of treating the crystal with the same etching agent, are related to the structure of the monoxide film which is gradually converted into ' dioxide in the atmosphere. Irradiated with shortwave light, this film generates an anomalously high negative photocurrent in the diodes due to the short- wave light being absorbed by the film. Gamma irradiation of germanium in moist atmosphere reduces the value of R. Ipparently, irradiation,of the germanium surface causes the formation of a film resembling the monoxide film. Indicative of this is the existence of the anomalously high negative photocurrent. Gamma irradiation of germanium,'protected from moisture, has no effect on R.

TITLEs Effect of gamma rays on germanium diodes SOURCE3 Nekotoriye voprosy prikladnoy fiziki, ~1961, .55 57 TEXTs Gamma irradiation causes a negative photoeffect in germanium diodes. The authors discovered this effect In A-7 (D-7),diodes, and reported on it earlier (Izv. AN UzSSR, ser. fiz. mat. nauk, 1960, no. 2). They assumed that this effect is due to inhomogeneities in the volume (Frenkell defects). The negative photocurront depends on the temperature and the spectral distribution of light. It increases with increasing frequency of the illuminating light. In the photocells examined, the in- crease in photocurrent was particularly striking atlozo.61b. For waves ty longer than 0 '8~,) the negative photocurrent is praotically vanishing. This means that it is due to the light being absorbed by the oxide coating and not by the surface-near layer. This was confirmed by, a series of experiments. Gamma irradiation of germanium in moist atmosphere causes Card 1/3 30 119, S/608/61/000/000/004/007 Effect of gamma rays on ... DIO/B102 the formation of a film on the surface whose reflection coefficient is similar to that of monoxide-coated (etched) germanium. This results'in the occurrence of the characteristic negative ph6tocurrent. Thus, the strong change of the diode characteristics is not only, due to inhomo- geneities of the crystal lattice but also to the,conversion of the dioxide coating int6 monoxide. Since surface electrons.are transferred to the monoxide coating, it is assumed that it is negatively~charged by.applying a voltage in the blocked direction. This resultu in the formation of holes in the surface-near "layer that provide a channel forexcess con- ductivity. Light absorption transmits the electrons from the acceptor levels to the conduction band of the coating, and from theret overcoming a potential barrier, to the volume of the germanium. The oxide coating is positively charged due to accumulation of bound holes, which reduces their concentration in the channel and, subsequently, the reverse current. This"model permitted to find empirical formulas for the excess reverse current and for the photocurrent in a germanium diode. The transient characteristics of the diode were computed, experimentally verified, and graphically compared. They were found to agreq fairly well. After' applying a voltage, the reverse current increases, whereas it decreases Card 2/3 49 5/6 '0 61/000/000/004/007 B140R - Effect of gamma rays on ... 31 102 when the light is turned on.

This theory incorporates the following two assumptions: 1) the solid behaves as an isotropic continuous medium as far, as thermal vibrations area concerned and (2) all the deductions from the theory obtained for a monatomic substance automatically hold for a diatomic; lattice. The present authors point out that both these assumptions are not strictly correct. In the majority of papers concerned with the X-ray measurement of 0 as a function of temperature, attempts are made to obtain informatIon on the corresponding change in the Interatomic forces. However, analyais of experimental data has led the present authors to the conclusion that the characteristic temperature as measured' Card 1/4 S/139/6o/ooo/o66/015/032: E032/9414 Determination of the Characteristic (Debye) Teinpera'ture by X.-Ray Methods by the X-ray method, cannot be a simple charac.barilstic of the interatomic forces in the lattice of a solid solution. Among the points quoted in support of this conclusion are 1) small changes (of the order of 1 or 0 at*) in the 2~ concentration of the second component give rise to large changes In (S) (20 to 30%) MA.111ina, V.K.Ki-itskaya, Ref.5)., such a change In cannot be due only to a 6hanglb in the interatomic forcesi 2) the characteristic temperature 9 ~is irx-eversibly dependent on the heat treatment to' which the alloysi haire been subjected and is not uniquely determined by the shoxt-range order parameter on the first coordination sphere'; 3) V.A.Illina et al (Ref.7) pointed out an analogy bet-een ED and YounglB modulus E in their dependence on heat~treatment. Analysis of numerical data for 6(E)/49 and 4%E/B shows that the observed correspondence is only apparei-st. I The debya theory predicts that (E? - -/T so that &9/9 %x 1/2(AE/E) - Experimental data,, on the other hand, show that 0-*11 changes by Card. 2/ S/139/60/060/006/015/0322, E032/E414 Determination of the Characteristic (Debye) Temperature by X-Ray Methods 20 to 30% while the corresponding change in E, is less than 3 or 4%; 4) finally, V.I.Iveronova et al (Ref.8).and S.A.Nemnonov and Finkel'shteyn, L.D. (Ref.9) have shown that~ the measured values of (D are smaller in the:ordered than in the unordered state (in the case of Cu3Au, N'3Fe, Fe3Al). The present authors argue that the characteristic temperature as measured by X-ray methods, depends not only on the interatomic forces but also on other factors such as the spectrum of thermal lattice vibrations, the relation between the dynamic and static displacements, variation of the mean square static -nt 2 displaceme u,t with temperature etc. It is concluded-that~ no definite conclusions can be made about changes in the interatomic forces in the lattice on the basis,of the X-ray, measurements of alone, There.are I figure and 15 references: 9 Soviet and 6 non-Soviet.
