ABSTRACT: The transient occuring during switching of a p-n-p-n junction is
investigated. Using continuity equations, expressions describing the distribution
of concentrations of nonequilibrium carriers in the base regions are obtained. An
expression is obtained for the minimum delay time during switching of a four-layer
system. It is shown that with the lapse of delay time the increment of current
through the sandwich system is described by an exponential law. A comparative
analysis is made of the transient response of switching of a p-n-p-n junction and a

TITLE: VKDL-type diffused silicon avalanche power rectifiers 1~
SOURCE: Elektrichestvo, no. 7, 1966, 56-59
TOPIC TAGS: semiconductor rectifier, silicon controlled rectifier
ABSTRACT: The development is reported of new types of diffused silicon power
rectifiers. The rectifiers, i ~.ch Kcan be operated s ely under high peak inverse
voltages, differ from conventionall-diffused silicon'rictifiers in that~ due to specialt
preparation of the p-n junction, the possibiTity of local electric breakdown, at the
intersection of the p-n junction with the surface is eliminated. Therefore, under
peak. inverse voltages, the process of avalinche breakdown takes place in the central
section of the junction, while large power is dissipaLed in the inverse direction. L-
In 1964, the Leningrad Physicotechnical Institute im. loffe, AS USSR, in COODeration
with the "Elektrovy :Ky4mite~' " Plant developed a series of such rectifiers bearing the!
desi,~_,nations VKDL-100, VKDL-200 and VKDL-350 for 100, 200, and 350 zmip, respectively,

bilitylof,furface breakdown. The p-n junctions were made by the method of DhoSDhorus
boron"Andibluminum diffusion. The boron p-n junction was 18 mm in diameter with a
planar guard ring 2 mm wide. The thickness in the diffused layer in the central
section of the silicon plate was 60-80 1j, and in the region of the guard ring,
120-160 p. The thickness of the diffused layer formed by phosphorus on the sidd 6f
the base contact was 20 ti. Typ i cal volt age-inverse current characteristics of dr- rectIliers in the
breakdcwn region at 5DO and 800 v are shown in Fig. 1. The characteristics correspond to
the central p-n junction. The breakdown voltage of the p-n junction in the guard
ring exceeds that of the central p-n junction by 250-600 v depending on the initial
silicon resistance. Dependence of the dynamic resistance of avalanche rectifiers on
inverse current is shown in Fig. 2, and the voltal-e-forward.current characteristic
in Fig. 3. With respect to the forward voltage drop, the above devices are divided
into three groups: those with a 0.4-0.5, 0.5-0.6, and 0.6-0.7 v forward voltage
drop for a nominal current. The inverse current under nominal conditions for all
rectifiers does not exceed 5 ma. The lifetime of the avalanche rectifiers is up to
25,000 hr. The number of thermal cycle's ranging from -50 to+1/40C should not exceed
5000 during the entire lifetime. The rectifiers can be connected either in series or
in parallel. Wben connected.in parallel, they should have equal forward voltage '
drops. Orig. art. has: 1 table and*8 figures. (JR]

ItiMe T. required for the anode voltage to decrease to 0.9 VA (where VA is applied
1,oltage to the anode); front time Tf required for the anode voltage to fall from
'0.9 VA to 0.1 VA; and the settling time T. required for the anode voltage to drop from
10.1 VA to a value determined by the semiconductor structure. These times were
,studied as functions of amplitudes and time durations of square-wave pulses applied
to the anode and control base (VA and VC) and of the hole lifetime in the thick base.
The square wave pulses VA had amplitudes between 20 and 125 v, durations of 50 to
150 usec, and a f!requency of 50 cps. The VC pulses bad the same frequency as-those
applied to the anode, but were shifted in time; their current and time duration was

ABSTRACT: This is a continuation of earlier work on deep lying p-n junctions (Radio-
tekhnika i eleL-tronika v. 9, 56, 1c,66) and deals with microplasma phenomena occurring
breakdown of deep p-n junctions prepared by diffusion,of boron in n-t e
in cascade yp
silicon. I-lost earlier investigations were limifid to microplasmas produced at the
emergence of the D-n junction to the surface. The present investigation deals with'
Junctions that have a large depth (40 - 100 p). Since the radiation from the micro-
1plasma is practically abs,:;.:-bed by the silicon, the data on the microplasma defor--a-
tion was obtained by studying the character of breakdown of a large number of cascade
nicrodiodes prepared on a single silicon plate by photolithography. Protection
against surface breakdown was afforded by a guard ring. Tbe junctions were prepared
by a procedure described by the authors earlier (Elektrichestvo v. 7, 56, 1966). By
studying the oscillogram of the inverse volt-ampere characteristic of the diode

during the breakdown it was possible to determine ihe distribution of the micro-
plasmas over the area of the junction, the volt-ampere characteristic, the variation
of the microplasma. temperature with current, and the geometric dimensions of the
microplasma. The results show that the microplasmas are distributed quite uniform.2y
over the area of the junction. Their number can be quite large, and the breakdown
voltage can differ greatly from Junction to junction. The breakdown volt-ampere
characteristic can be approximated by an exponentia:l function. The calculated geo-
metrical dimensions of the microplasma'were found to agree well with'the experimental~
data. Orig. art. has: 4 figures,, 8 formulas, and 1 table.

Abstraot I The derivation of,polyamides:from diglycolic acid and hexamethylenediamine,
is described. Mixed polyamidea were also obtained from 6 -carbolactam and
salts of di-(gamms-airdnipropyl) ether of ethylene glycol with adipic acid
and from salts.of adipic acids with hexamethylenediamine at various ratios
of the basic substance. It was established that the addition of ethereal
oxygen to the polyamide macromolecule chain leads to a reduction in the melt-
ing point and to an increase In solubility in comparison with polyamides
having no ether bonds. :.The properties of the polyamides are listed. Six

ABSTRACT: In this paper the reaction of hydrazine with a number of di-
carboxylic acids and their derivatives at a molar ratio of
2:1 was investigated with eucosane dicarboxylic acid, sebacic-,
azelaic-, adipic~-'-, glutaric-, succinic-, and thiodivalerianic
acid. The substances obtained were investigated as to their -
thermomechanical and mechanical properties (Figs 1,2). A sur-
plus of 90 mol % hydrazine was found to be the optimum quantity
for the purpose of obtaining pure products with respect to the
quantity of hydrazine necessary for the formation of the di-
hydrazide of the individual acids. The structure of the poly-
triazoles obtained on the basis of the investigations carried
out is assumed to be the following*

ABSTRACT: In a previous paper by the same authors (Ref 1) the poly-
condensation of various dicarboxylic acids with hyd-~,azine was
investigated; it was found that in the polycondensation of
sebacic acid with hydrazine the nitrogen content of the di-
hydrazide obtained was somewhat lower than the theoretically
calculated content. Agreement with theoretical calculation was
obtained only by -using a certain(surplus of hydrazine. Ref-
erence is made to V. W. Fischer Ref 2), who found it neces-
sary to use the excess hydra2ine in order to prevent the pos-
sible formation of polyhydrazides and poltoxadn-azoles which is
possible in this reaction. In connection herewith the poly-
condensation of hydrazine in the following dicarboxylic acidsz
sebacic acid, phthalic, isophthalic, and terephthalic. acid was
Card 1/2 investigated in this paper. The characteristics of the salts

On 'he Problem of the Formation Mechanism of Polyp-inotriazoles
obtained are given in a table. On the one hand, the polycon-
densation with equimolar ratios hydrazine : dicarboxylic acid,
where polyhydrazide was obtained, was investigated, and on the
other, the molar ratio 2 (and more) ; 1 resulted in polyamino-
triazole by the application of pressure. The reaction scheme
is assumed to be the following: First, the dihy-drazide is
formed immediately from "he salt of the dicarboxylic acid and
hydrazine. The dihydrazine can then be converted under pressure
nearly quantitatively into an aminotriazole compound with
separation of water.- For the conversion of polyhydrazide into
the aminotriazole ring an additional surplus of hydrazine is
finally necessary. This surplus has a maximum. If the maximum
is exceeded, this causes impurities due to polyhydrazide and
its hydrolysis-products. P01Y-4-amino-1,2,4-triazole is re-
presented. There are 1 'able and 2 references, 1 of which is
Soviet.

TEXTs Polyhexamethylene adipamide of molecular weigII23,500 was subjected
to heat treatments at 3500C (in 12 current) and at 380 and 4000C (in an ,
autoclave and 12 atmosphere) for several hours each, and the resulting de-
composition products were investigated. *At 3500C, a steric (three-
dimensional) crosslinking of the polymer occurs with cleavage of NH* and
3
C02* At 3800C and over, a primary hydrolytic cleavage of the amide bonds
sets iP, followed by a separation of C029 cyclopentanone, asinest and KH 3*
The presence of CO and low hydrocarbons in the decomposition product
points to an additional hosolytio cleavage of the -CO-NH- bonds. The

TITLE: Thallium Distribution in the Dust Collecting System of a Lead
Plant (Raspredeleniye talliya po tsekhu pyleulavlivaniya svint-
sovogo zavoda)
PERIODICAL: Byul. tsvetn. metallurgii, 1957, Nr 11-12, pp 51-53
ABSTRACT: TI loi"'es, as well as the distribution of this element in the
dust- colfecting system, were investigated. It was established
that total Tl losses throughout the dust-collecting section of a
lead plant may attain 24.9%, but that they can be reduced by
one-half by means of extracting Tl from the drain water and by
discontinuing the practice of discharging gases into the atmo-
sphere without preliminary purification. It is essential that
roasted dust from electrofilters be systematically processed
in the cadmium shop. This will sharply increase the proportion
of T1 in the finished products.
