SPACE-CHARGE LIMITED CONDUCTION IN GEXSE100-X

The present paper reports the measurements on space charge limited conduction in vacuum evaporated thin films of Ge(x)Se100-x where 5 less-than-or-equal-to x less-than-or-equal-to 40. Current, at high fields (10(4) V cm-1), could be fitted to the theory of space charge limited conduction in case of an uniform distribution of localized states in the mobility gap of these materials. The results indicate that a minimum density of localized states occurs at x = 22 which is in agreement with the other experiments reported in the literature.
