Surface Properties of Semi-conductors SOV/139-58-4-13./30 of AlSb, InSb and Ge. The results are silmmarised thus: litching eliminates the broken-up fine-grain surface layer and thereby reduces the concentration of surf acceptors. The surface properties of type AKI'V compounds show considerable analogy with those of germ 'um.

This work investigates the dependence of the sign of the conduction of AlSb and InSb on the dimensions of the grain. As original material AlSb- and GaSb-preparations of the n-type were used, which were obtained by the method of alloying. The author produced layers of AlSb, In Sb, and GaSb with hole conductivity by vaporisation of the named finished compounds in vacuo. The preparations obtained by the method of alloying were crushed mechanically to a certain degree of smallness. The ave:,!age dimensions of the jrain were controlled by a microscope. In the various states of the grinding the sign of the thermoelectromotive force was ascertained by the compensation method. For this purpose Card 1/3 the powder was fixed between two copper or nickel-plated The Influence of the Surface on the Sign of the Conduction 20-3-18/59 In AlSb and InSb electrodes, bstween which a constant temperature difference of Go to loo was kept. In case of these measurements the total thermoelectromotive force, which is determined by the avera-e dimensions of the grain in the powder, is obtained. In case of further refinement of the grain the thermo- electromotive force decreases. At grain dimensions of 2 to 3 V it became very low; on occasion of further refinement of the grain it changed its si&n and increased again. A storage of the powder over long periods and a heating in vacuo up to 200 to 3000C did not change the sign of the charge. The thermoelectromotive force was measured in that case directly in a vacuum device. For the comparison measurements were made also at pressed test pieces. The electromotive force of these pressed test pieces was some- what higher because of the bett,~r contact between the grains. To control the method and for a comparison all the measurements were performed also with a preparation of n- -germanium. The results obtained here show the following: The development of the surface of the test pieces of the AlSb and of the InSb leads to the appearance of a p-con- Card 2/3 ductioji.

Fo - - ----------------- TITLE: Investigation of the Surface Electrical Conductivity of Germanium Single Crystals k PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 3, PP. 381-387 TEXT: The authors investigated the influences exercised by various kinds of processing and coating on the conductivity of samples of germanium single crystals. Here, they report on the theory, experiments, and results obtained from the investigations of these effects. In the first chapter of this paper, some conceptions on the surface state of a semiconductor are discussed. The nature of the electron surface states in a semi- conductor may vary: 1) Tamm levels (I. Ye. Tamm, Ref. 6), which always occur in a bounded crystal; 2) levels occurring due to increased concentration of impurity ions in the layer near the surface; and 3) levels produced by atoms which are bound to the semiconductor atoms by covalent forces. Further, the conclusions drawn on the surface states by Card 1/4 81347 Investigation of the Surface Electrical 9/181/60/002/03/01/028 Conductivity of Germanium Single Crystals Buu6 B017 R.- L..,Xyuller et al. from results of etc',ing experiments are discussed, and two cases of influence exercised by the surrounding medium on the surface are discussed. The authors themselves conducted their investi- gations in n-type and p-type germanium single crystals: To increase the surface effects, very thin samples were used (0-15 - 0.2 mm). These platelets had a size of 5 - 3 mm with two contacts each. nn alloy consisting of tin with 5-10% antimony served as "solder". Before the measurement was made, the samples were etched for 5 - 10 minutes in boiling hydrogen peroxide and then washed in distilled water. The further preparation for the measurement is described. The current passing through the samples was of the order of some milliamperes. Resistance was measured by means of a nFITS-1 (PPTV-1):"potentiometer according to the compensation method, a mirror galvanometer serving as zero instrument. The temperature dependence of the resistance was investigated (see Fig. 2), after which the samples were taken out of the ampoules, processed or coated with lacquer, and the measurements were then repeated. The results of measurement of the temperature course of resistance on etched and processed samples (ground with sand or methyl alcohol, or treated with Card 2/4 "K 81347 Investigation of the Surface Electrical S/181/60/002/03/01/028 Conductivity of Germanium Single Crystals Boo6 B017 paraffin), or on samples coated with lacquer are shown in a Table. Pigs. 3 and 4 show the resistances of samples coated with lacquer as a function of temperature. n-type germanium tends to reduce the relative resistivity with increasing temperature, whereas p-type germanium shows a certain increase (Fig. 5). As may be seen from Fig- 3, the electrical resistance of the layer near the surface decreases in n-type germanium for samples with lacquer coatings, whereas it increases in p-type germanium. The authors try to explain some further results of the various processing methods. Hence, e.g., the increase in the resistivity of n-type germanium treated with CH30H is explained by the interaction between the OH-group and the surface dipoles as well as by the resulting reduction of the electron concentration in the layer near the surface. The decrease of the resistivity of both germanium types after a treatment with finest sand is explained by the occurrence of surface conductivity. Student E. A, Anpilogova took part in the experiments. There are 5 figures, 1 table, and 9 references: 6 Soviet, 2 US, and 1 English.

A Study of Some Physical Properties of Polycrystalline GaAs PERIODICAL. Izvestiya vysshikh uchebnykh zavedeniy, Fiz'AIM, 1961,.No.2, pp.66-70 TEXTz This paper was first reported at the Third Conference.of Schools of Higher Education on Semiconductors and Dielectrics, Leningrad, 1960. The resistivity, thermoelectric power and the Hall coefficient of polycrystalline specimens of gallium arsenide were measured. The original material was synthestmed directly from arsenic and gallium and was zone refined six times (this will be described In a. separate paper). The final specimens were rectangular In form - and their dimensions were 2 x 2 x 7 mm3. The resistivity and the Hall coefficient were measured with the aid'of ohmic tin contacts fused into the specimens in a vacuum at temperatures of the order of 6oo to 700*C- Before me-asurements were begun, the specimens Card 1/6 21513 S/139/61/000/002/Oo8/oi8 A Study of Some Physical E032/E414 were immersed in a solution containing 20 ml of NaOH and 4 M1 of 30% H202 (G.A:.Averkiyeva, 0,,V,Yemellyanenko, Ref. After this treatment they were washed in boiling distilled water. Fig.1 shows the temperature dependence of the electrical conductivity and carrier concentration calculated from the Hall measurements under the assumption that the hole-concentration was negligible. It is estimated from the slope of the curve representing concentration as a function of temperature that the activation energy of the donor impurities was 0.12 ev.

Using the Pisarenko formula (Ref.2) the magnitude of the effective mass of the carriers was estimated to be of the ordbr of 0.27 moo The experimentally determined temperature dependbnce of the concentration was compared with its theoretical value computed from the formula Card 9/ 6 S/139/61/000/002/OoB/ol8 A Study of Some Physical ...

The sam- ple production. procedure is described. The depth of the junction was measured by taking an oblique cut through the junction and mea- suring the sign of the rectification with a pointed cold probe. The usual depth for boron was 8-10 microns. The protective film was found to reduce:the breakdown voltage of the junction, which was restored to its initial value after removing the protective film (by etching). However, the protective film did make the junction istable against tropical moisture conditions. The reason for the re- I duced breakdown strength in the protected junctions is analyzed from the point of view of redistribution of the doping impurity during the course of oxidation, the one-dimensional surface-breakdown the- ory, and the Shockley theory. All indicate that one of the probable 'imechanisms for the reduction in the breakdown voltage is the in- crease in the impuri-ty.'concentration'on the interface between.the silicon and the silicon dioxide.

In the first part of the present paper the authors investigated, using electron diffraction analysis, the structure (in particulm hase 14he p composition) of the sulfide layer created on the surfa`c",~'o'f _ar'S-fmonocryistal processed in a special suffidation tank. The experimental results obtained for the lattice plane distances are in good agreement with the theoretical data for SIS. The second part of the paper is devoted to the study of the structure of germanium sulfide layers produced on the surface of germanium. monocrystals during their reaction with sulfur vapors. The Debye diagram utilized the Cit K. line. The comparison of the experimental and theoretical values for various e lattice plane distances showed that the stable chemical compound formed to Indeed prystallin GeS.

This spectrograph makes it possible to maintain an ultra- constant target temperature and to easily replace the target and the cathode.. ~.The desian should satisfy the followinz co'ditions: 1) light emitted by the. n d cathode should not strikd the target; 2) relative error in the determination of the electron energy should not exceed 1-2%; and 3) the target should have maximum protection against impurities resulting from dissociation of the cathode and against the condensation of the'vapors of organic substances. 1 f The resolving power of the spectrograph was D-1 - 0.9%. Maximv-i density Card ACC NR: AP7001940 of'the beam current du--ring op-eration with a tungstnn cathode was approxi- mately 10-6 amp/cm2. Pulse rise time during Ipulsed irradiation was 0.2 psec. The spectrograph was used to study changes of the surface energy states of germanium acted upon by electrons with an energy of 100-400 ev. The elec- trons generate a positive charge in the natural oxide film, coating the .,germanium surface. As a result the surface conductivity shifts from p- to n-type. The shape of the curve representing the dependence of the-sur- face recombination s on the surface potential Os for germanium processed in H.0 changes considerably during electron irradiation. In addition to the 4 2 fundamental stable maximum S, a second induced maximum at < 0 with a large amplitude value S appears as a result of irradiation. The amplitude of "he induced maximum diminishes spontaneously to the initial level 10 to 15 min after irradiation. It is shown that'jthd-fiature' of the induced maxi- mum S is associated with the recombinationlicqnters, whose effectiveness depends on the positive'.charge appearing in ~he oxide film.- Orig. art. has: 1 formula and 5-figuti--s-.

The performance of this detector in the presence of a square shaped input signal Is examined for the case of higher harmonics and subharmonics and various types of generators. The degree of the suppression of undesirable harmonics, leading to the possibility of misleading operation of the element, is considered. Simple working formulas, which proved to be in satisfactory agreement with the experi- mental findings on the development of an element with 10 stable states, are presented.
