3. Capacitancevoltage measurements in selectively doped ALGAAS/GAAS heterostructures N.B.Gorev, I.F. Kodzhespirova, E.N. Privalov gallium arsenide, selectively doped heterostructures, Schottky barrier, barrier capacitance, capacitance–voltage measurements Vestnik KhNU ¹853 Pages. 37
The dependence of the measured apparent capacitance of selectively doped AlGaAs/GaAs heterostructures on the amplitude of the measuring ac voltage is calculated numerically. An expression that gives the measured apparent capacitance as a function of the true capacitance and the above amplitude is derived. Using this expression and the results of the above numerical calculation, it is shown that capacitance–voltage characteristics of selectively doped AlGaAs/GaAs heterostructures, which feature steeply dropping regions, may be measured at moderately small amplitudes of the measuring ac voltage (of the order of 100 mV) at the expense of taking measurements at two different amplitudes

6. Compromising emanations: overview and system analysis N.N. Gorobets, À.V. Trivaylo compromising emanations, nearfieldzone, electromagnetic, radiation, time domain Vestnik KhNU ¹883 Pages. 8388
The problem of compromising radiation of spurious signals in the near, intermediate and far zones of observation in time domain are considered. The Compromising emanation system analysis for finding spurious radiation is proposed. The goal of the given approach is to speed the development of technical protection of information. In approximation of the given current distribution it has been suggested a solution considering the influence of the nearfield effects upon directional characteristics of spurious signals radiation. The application of the new method allows us to investigate compromising of technical means in time and frequency domain.
