Abstract : Nine out of twelve cats endured well the
prolonged (from
18-ff' to 23 minutes) exclusion of the heart from the
circu-
lation while a prophylacted complex was employed:
ether-
o3agen anesthesia, hexone, vitamins B, and C, glucose
and
general chilling. Full restoration of the functions of
the central nervous system occurred in the same
sequence
as, but more rapidly than after aphyxial. cessation
of the
heart. Of the animals which survived, in two focal
chan-
ges were observed In the hippocampus, in two others

Abstract: By the method of photoconductivity under
constant illumination a
study was made of the photoelectric properties of iodides
and bro-
mides of Ag and Tl,, having adsorbed thereat organic
dyestuffs
(cyanines, thiazines, xanthines, triphenyl-methanes,
etc). More
than one bal of the investigated dyestuffs sensitize the
photo-
effect (PE) in Agi. These dye include photographic
sensitizers as
well as dessusitizers. Dyestuffs which do not affect the
sensitivi-
ty of photographic emulsions do not sensitize the FE in
AgI. Spec-
tral distribution of additional (induced by the presence
of the dye-
stuff) PE coincides with the absorption spectrum of the

ABSTRACT: Various authors already reported on investigations on
the
optical sensibilization of the internal photoeffect in in-
organic semiconductors by organic dyes, the sensibilization
without impurities in the bromide, howevert is not explained
yet (Refs 1-10). In this paper above all the influence of
bromine vapor (at 0,1 torr) on dyed and undyed AgBr- and TlBr-
layers is inyestigatedl it turns out that the adsorption of the
bromine vapor has a clear influence upon the intensity as well
as upon the spectral distribution of the photoeffectl e.g*
TlBr dyed by malaohite green ahows an intensifioation of the
photo-e.m.f. and a shift of the spectrum towards greater values

sorption 400-450 m/j- after the adsorption 500-750 ml.4 with
a maximum at 700 m~&~. If bromine partly is desorbed the value
of the photo-e.m.f. is reduced to about half of it without
displacing the position of the spectrum (Fig 1 - TlBr, Fig 2 -
AgBr). The position of the maxima of the photoeffect coincides
with the maximum of the adsorption of the dyes. A dying by
methylene blue does not only change the intensity of the
sensibilized photoeffect but also causes a displacement of the
ipeotral distribution towards the range of the adsorption of
the dye. The photoeffect aensibilized by methylene blue has a
maximum at 680-700 m/:t., after the adsorption of bromine'
vapor at 780-800 m/4,(Fig 3 - TlBr, Fig 4 - AgBr). The author
renders his thanks to A. N. Terenin, Member, Academy of
Sciences, USSR, and Ye. K. Putseyko for their interest shown in
the work and for valuable suggestions.

TEXT: In order to define precisely the mechanism of photoeffect
sensitiza-
tion, the relaxation times and the photocurrent carrier~signs
were determined in
non-dyed and dyed layers of TlI and AgI for different region6 of
the spectrum.
The a'ign of the carriers was determined by the capacitor
method. The photocurrent
relaxation times were measured by the method of N. A. Tolstoy
and P. P. Peofilov
("Uspekhi fiz. nauk *11, 196o, 41, 44) on'a taumeter with an
exponential sweep. It
was found that the sign of the sensitized,photocurrent carriers
does not depend
on the sign of the photocurrent carriers in the dyes, but it is
determined by the
photoeleettic properties of the semiconductor. The role of the
dye consists only

of Academician A.N. Terenin. Several organic

colorants were tested for their ability to lumi-

and the oxides of certain

metals. On these semiconductors,

source of light for the chemical stimulation was
a chromatic device of high light intensity with
diffraction lattice. The investigated colorants
did not luminescence in the adsorbed state of ZnO,
PbO, and the silver and thallium halogenides. But
the same colorants adsorbed on MgO, BaO, TiO,,
paper, cotton wool, gelatin and polyvinyl la quer
displayed an intensive luminescence. It does not
seem to be quite impossible that such substances
as PbO, AgBr, Tl&-, that have a red and orange
luminescence, are energetically sensitized by the
colorants.

TITLE: Effect of Illumination on the Contact Potential of
Some Semiconductors
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 128, Nr 4,
pp 691-694
(USSR)
ABSTRACT: First there is mention of previous papers in this
field.
V. P. Bogolyubov (Ref 8) investigated the influence of
illumination on the contact potential of selenium layers.
1. K. Vitol recently used a dynamic condenser for the
investigation of photoelectric polarization in alkali-halide
crystals. Scope of the present study is the examination of
the change in the contact potential of a semiconductor under
the influence of monochromatic illumination. Therefore,high
requirements had to be met by the condenser cell and the
amplifier device concerning sensitivity and stability of
operations. The article contains a description of the measur-
ing device. The condenser cell consists of a glass vacuum
vessel in which a semi-translucent platinum layer on a mica
sheet serves as vibrating electrode. The second electrode
Card 1/3 is a platinum-coated cylinder which is subdivided by
incisions

SOV/20-128-4-15/65
Some Semiconductors
into four sectors. The layer of the semiconductor to be
examined is put on one of these aectors by sublimation.
T he author determined the difference in the contact potential
between the platinum electrode and the semiconductor electrode
in vacuum and in air both for inorganic semiconductors
(TlJ(p),
CdS(n), Zno(n)) and for several organic dyes and determined
the spectral distribution of the contact-photoelectric
potential.
Two diagrams illustrate the spectral curves of the photoelec-
tric potential for layers of ZnO and TIJ, which were sen-
sitized by dyes. These curves are in accordance with the
spectral distribution of the photoelectromotive force and the
photoelectric conductivity of ZnO and TIJ layers (stained with
identical dyes). This method permits, besides the examination
of the spectra*1 distribution of the photoelectrical
potential,
also a judgment on the sign of the current carriers. The data
obtained with the described method concerning the sign of the
photoelectric current carriers are in accordance with the
results obtained by other authors who used different methods.
When illuminating the semiconductor layer from the opposite
Card 2/3 side the photoelectric potential changes its sign as
expected.

Effect of Illumination on the Contact Potential of
SOV120-126-4-15165
Some Semiconductors
According to V. Ye. Kozhevin and V. Ye. Lashkarev (Ref 18)
tile magnitude and the sign of the photoelectromotive power
of
the condenser investigated in 2 previous papers (Refs 10,11)
depend on the character of the insulating intermediate
layers.
To clarify this problem the author examined the contact dif-
ference of the potentials for TIJ and phtaloayanine between
the platinum e.lectrode and a layer of the semiconductor,
which
was in vacuum, in air or in contact with various insulating
media. In darkness the contact difference of the potentials
can be varied within wide limits (from -0.4 to +4.5 v). But
these variations were of no considerable influence on the
rate
and sign of the photo potential in the case of TIJ and the
phtalocyanine. The excess electrons and holes developed by
the
light diffuse either into the depth or to the surface and re-
combine subsequently. The author expresses his gratitude to
Academician A. N. Terenin for suggesting the topic and for
his
advice, and to Ye. K. Putseyko for his counsel . There are
3 figures-,' 1 table, and 20 references, 13 of which are

ABSTRACTS The authors investigated the effect of hydrochloric acid
and of some metal chlorides on the absorption and
luminescence spectra of magnesium phthalocyanine solutions.
On addition (in air) of a solution of ferric chloride
(FeCli.6H20) in acetone to an acetone solution of magnesium4/
phtha ocyanine, the blue colour of the solution changes to
olive green and the absorption spectrum is altered as shown
in Fig 1. The absorption bands of magnesium phthalooyanine
with maxima at 665 and 601 mp disappear and new absorption
bands appear with maxima at 707 and 682 mp. When the
solution is allowed to stand the latter two bands decrease
Card in intensity. After several hours new weak bands,
characteristic of phthalocy'anine without a.metal, appear
at 688 and 655 mp. Simultaneously a deposit is formed

which when dissolved in dioxane exhibits a spectrum of
phthalocyanine without a metal. Similar behaviour is
observed also on mixing of an acetone solution of
magnesium phthalocyanine with an acetone solution of
hydrochloric acid of lo-3 m/e concentration. These
experiments indicate that the central magnesium atom is
replaced by hydrogen and that this reaction proceeds via
an intermediate unstable complex which has absorption-bands
at 707 and 682 my. An unstable complex is formed also on
addition of Sbcl~, BnC14 and SnII+ to an'acetone solution of
magnesium phthalocyanine but in this case the absorption
bands of phthalocyanine without & metal are not observed.
Addition of bases such as pyridine, aniline or a
concentrated aqueous solution of potassium hydroxide,

TEXT: The authors investigated the photoeffect in thallium

oxide, which had been dyed by means of organic indicators.
Measurement of
the photoeffect was carried out in air and in vacuo, as well
as after
adsorption of anhydrous HC1 and NR3 vapor. Between the resalts
obtained
in air and in vacuum there was no difference. Aurin, safranine

thymolphthalein, bromothymol blue, Nile blue, and Congo-red
were used,
whose structural formula, reaction-pH, Amax and sensitizing

TlI and ZnO are given in Table 1. Besides, experiments were
made with
malachite green, erythrosine, and methylene blue (Fig. 3). The

summational photoeffect sensitized by the indicators changes in the
case
of TII after adsorption of HC1 only little, but the spectral.
distribution
changed in accordance with the absorption spectra of the dyes. After
adsorption of NH 31 the sensitized photoeffect decreased or had
vanished
altogether. In ZnO, on the other hand, the photoeffect vanished
after
adsorption of HC1. After desorption of HCI, ZnO again possessed the
initial sensitized photoactivity. The indicators thus sensitize in
neutral
form both the photoeffect of the p-type semiconductor TlI, and also
that
of the n-type semiconductor ZnO. In the protonized state (after
adsorption
of HCl), they are no longex able to sensitize ZnO, nor to sensitize
TlI
in the anionic state (deprotonized by NH3). These effects are
explained
by the change in the electron acceptor levels at the surface of the
semiconductor, which, in ZnO, are formed by the adsorption of
oxygen ions,
and in TlI by adsorbed iodine ions. The authors mention a paper by

PERIODICAL: Fizika tverdogo tela, V- 4, no. 6, 1962, 1542 - 1548
TEXT: The spectral characteristics of the internal photoeffect of
uncolored and colored TlI and ZnO semiconductors and of
phthalo6yanine
were investigated by four different methods in the region of
characteristic and sensitized sensitivity; (1) The photoconductivity
was determined at constant voltage and under constan~t
or'intermittent
illumination; (2) the longitudinal photo-emf in a capacitor with a
semi-transparent electrode was determined; (3) the changes in contact
potential and in the sign of the surface charge of the semiconductor
were determined with a dynamic capacitor under constant illumination;
(4) the photodieleotrio effect in a semiconductor layer was
determined.
The alternating signal of the photoeffect (150 or 600 cps) was
measured
with a resonance amplifier. A correlation between the absorption

spectrum and the photo-emf was found for metal-free phthalocyanine
in the
visible and ultraviolet spectral regions. No overlap of the two
spectra
could be found in phthalocyanine layers of the*same kind when
different
forms ofo,- and $-pigments were present in them. A correlation
between
the absorption spectra and the spectral curves of photoconductivity
could be established only for thin layers of organic and i*norganic
semiconductors. Differences appear for thick layers: weakly absorbed
light sets-free photoelectrons far from the surface, while strongly
absorbed light sets them free near the surface. The spectral curves
obtained by the four different methods for the sensitized
photoeffect of
ZnO, AgI, and TlI colored with different pigments agree with.one
another
and correspond to the absorption spectra of the'adsorbed pigments*
The
spectral curves of photoconductivity of AgI and TlIp obtained by
various
methods in the region of self-absorption of the semiconductors# do
not
agree with another. As in the case of phthalocyanine, the maxima of
photoconductivity obtained by m*aaurement * Of the photodialeatric ,
effect, the photocurrent, the photo-emf, and the contact potential
are
shifted to the short-wave side of the spectrum. There are 6 figures.

TEXT: A high-speed apparatus (Fig.-1) was developed to study, in
the
region of 350-1000 mit, the change in the spectra of
photoconductivity and
photo-emf of microcrystalline powder of silver halides uncolored
as well
as colored with cyanogen pigments. The semiconductors are
irradiated with
about 10- 6 W/cm2 using an incandescent or xenon lamp,*the light
of which
is modulated by a frequen6y of 600 cps. The spectral curve of the
photo-emf in the capacitor is obtained on an oscilloscope.
Measurements
~were made on uncolored silver halides and also on powder which
had adsorbed
organic sensitizers. The change of'the photoeffect in the
spectral.region
of the absorption edge is attributed to the formation of electron
adhesion levels by the products of photochemical decomposition of

ABSTRACTs The spectral response of photo omf was plotted and the
photocurrent and dark current carrier signs were determined for
brilliant green, crystal violet, malachite green$ and auratine
dyes, The spectral response of photo amf and the photocurrent

methods, and the dark current carrier signq from the Seebeck
effects,

s,ublimates) having a mirror-like surface (samples I), the above
deposits treated with ethanol vapors (11), or microcrystalline
preci-
pitates (III) prepared by repeated recrystallization from ethanol*
The following results were obtained: in air or in vacuum for 1, the
photocurrent and dark current carriers were electrons; in air and
va-
cuum for 11 and III, the carriers were holes. Evidently, contact of
the mirror-like films M with water o alcohol vapors causes them to
undergo rapid recrystallization to a slable form, fine crystals
(II),
with carriers of opposite sign. Adsorption of polar gases and vapors
on the dye can lead not only to a change in the form of aggregation,
but to the formation of impurity levels, both in the bulk and on the
surface of the dye film. In the case of compact mirror-like films
(I), the role'of the dye surfacel which interacts with the
surrounding
atmospherep is negligible in comparison with the role of the bulk of
the sampleo Thereforej the negative photocurrent carrier sign
whichim'
inherent to the dye is also preserved in air* In the case of minuts-
crystals (11 and 111) in which the molecules of the dye are

ABSTRACT: The authors refute somi! q ttIie earlier arguments, In

that the,capacitor method,, wl, dilly used for the Investigation of

perties of semi conductors-'fA4j'1'1-tbe used to determine the sign

,carrier charge. They cite, in particular, the frequently observed
"repolarization"
phenomenon, wherein an additional longer-wavelength band appears in
the photo-cmf
spectrum, with a photo-emf of opposite sign,. and show that allowance
for this
phenometion explains the anomalies on the basis of which the
capacitor method was
deomed unsuitable. Two hypotheses are advanced to explain the
"repolarization,"
and an experiment is described by.wbich it has been demonstrated that
this pheno-
menon is the result of the interaction taking place in the
semiconductor betueen
the carrier diffusion (Dember effect) and carrier drift in the field
of the near-
surface charge, producing anti-barrier bending of the bands at the
illuminated
surface. The photoeffect produced in the capacitor can be explained
therefore by

assuming the photoconductivity to be monopolar (and not due to
rectifieraction,
as hitherto believed), and can therefore be used to determine the
photocurrent
carrier charge provided an additional investigation of the photo-emf is
made to
determine the relative contributions of the two types of carrier
motion. The
conclusions are corroborated by experimental data on the photo.,;emf of
AgBr, AgCl,
T11, and ZnO. It is also pointed out that the capacitor method can also
be used to
investigate surface states of semiconductors in vhi the-surface charge
can be
varied. "We are grateful to Academician A. N. Terenfltior continuous
