:TITLE: Observation of the motion of electrical domains in n-type germanium, with a
partially compensated upper acceptor level of gold

TOPIC TAGS: electron capture, electron donor, temoerature dependence, electric field
JABSTRACT: The motion and velocity of a strong electrical field (domain) was observed
in samples of germanium containing Au and Sb in the range of temperatures between 15
and 350K. The electrical instability is due to the dependence of electron captUL'U 1H

region of themal ge~aration of electrons in the sample, velocit-I depends exponential-
ly on temperature and the activation ene-.,,y is -0.04 ev. In the region in whi ch elec-
trons are generated primarily by the thermal- background from the gold acceptor level,

fat these temperatures. At lower temperatures, domain motion depends but, --lightly '-I
temperature, and a-7rees with the theoretical equation of B. K. Ridley (Phys. Let., If,
1105, 1965). The voltampere characteristic is liiiear and there is no instability below'!
1150K.because conductivity in the samples is governed primarily by the ionization of
icarriers the shallow donor level, which is filled by electrons as a result of OP-
Itical recharging. It is shown that inhomoge-ne.-ties irt the sample strongly affect the
nature of domain motion. The domain forms in tho region of the largest stationary
field in the sampla and travels toward the field, disappearing at the anode or in the
region of th;:. weak field ahead of the anode. The authors thank V. L. Bonch-B.-Uyevich

TITLE: A Shortwave Vertical Antenna Operating with a
Progressive and a Standing Current Wave
PERIODICAL: Slaboproudy obzor, 1960, Vol. 21, No. 12,
pp. 730 - 734
TEXT: A wideband vertkal antenna operating at short waves
is analysed. The top load of the antenna (Fig. 1) consists of
a resistance R and a terminating capacitance C . The
current flowing through the apacitance C closes to the
receiver through the earth surface and produces some radiation.
The power lost in the eArth surface and the power radiated
can be taken into account by means of two equivalent resistances~~
Rel and Re2 , which are connected in series with C . In
general, the second component can be neglected, i.e. Re2 = 0
The load of the antenna is therefore given by

If C -!~OQ it can be assumed that the antenna is terminated
with an ohmic resistance and the condition of the appearance
of a progressive wave is therefore given by:

where Z 0 is the characteristic impedance of the antenna;
this is approximately expressed by;

length to its height above the Earth
However, in general, it is not possible to meet the condition
expressed by Eq. (2). It is therefore not possible to get a
perfect progressive wave and a standing wave is also produced.
In general, the terminating capacitance is of the order of tens
of pF so that its reactance in the bitnd of short waves is of
the order of hundreds of ohms. The antenna cannot easily be
matched and the standing-wave ratio is quite high. However,
this situation can be overcome at least at one frequency by
connecting a series inductance L to the terminal of the
antenna. Now, at the resonant frequency of LC the top
terminal of the antenna is effectively grounded and the standing
wave is negligible. From the above, it is seen that, in
general, a combination of progressive and standing wave is
produced in the antenna so that its current can be expressed by:
iz = Io [(1 i~ p) . eja(t-z) -j2p.sinla(t - Z)jj (5)

The total field is given by the sum of the components
expressed by Eqs. (8) and (10). On the basis of the above
formulae, it was possible to determine the radiation diagrams
and input impedances for the antenna with and R, L, C load.
From these diagrams it is found that the radiation patterns
of the antenna do not differ substantially from those of a
similar antenna with a simple standing wave; the only
substantial difference Is observed in the shape of the side
lobes. On the other hand, the presence of a progressive wave
in the antenna current results in a "smoothing" effect of the
input resistance of the antenna. It is found, in particular,
that with a suitable L and R =-R 0 (where R 0 is the
characteristic resistance of the antenna) the impedance
characteristic at frequ3ncies between 4 and 14 Mc/s is
comparatively uniform.

ABSTRACT: A graphical-numerical method is given for the calculat�cn
of antenna radiation patterns. The current distribution
on the antenna is substituted by a piecewise-constant I Z
distribution. It is assumed that the Earth has infinite 93
conductance, The following cases are considered.,
radiation of a perpendicular conductor over the surface
of the Earth; radiation of a horizontal conductor over
the surface of the Earth; radiation of a capacitance-
loaded antenna.
