The transient photoconductivity of additively coloured KCl crystals has been measured between 10 and 90°K using zone refined KCl single crystals, air grown KCl, and KCl+SrCl2. Crystals with various impurity contents differ both in the amount and the temperature dependence of photoconductivity. Pure crystals after previous illumination at various temperatures show the same behaviour. The observed differences may be explained by trapping processes. From electrical glow curves it is concluded that all crystals contain a large number of traps. 相似文献

Measurements are described, which show the variation of conductance versus temperature of evaporated layers of leadselenide in presence of low partial pressures of selenium. The interaction between the selenium vapor and the leadselenide film is revealed by the reversible dependence of conductance on temperature and partial pressure of selenium.
The measured relationships are quantitatively understood on the following assumptions: The reactions of lead resp. selenium vacancies with selenium particles, adsorbed from the vapor phase, are limited to the surface region of the PbSe crystallites. The interior of the crystallites remains unchanged.
