Effect of low-energy X-ray radiation on the electrophysical properties of silicon crystals of n- and p-type conductivity

We study the kinetics of the photovoltage decay in silicon crystals, caused by the effect of lowenergy (E = 8 keV) X-ray radiation. A correlation between radiation-induced changes in the short-term and long-term components of the photovoltage decay and the charge state of the surface, determined by measuring the surface distribution of the amplitude and decay time of the photovoltage, is found.
