摘要
At not too low temperatures the dc conductivity sigma of amorphous chalcogenides is thermally activated. In determining sigma //o and E//A of a-Ge//3//0Se//6//0Te//1//0 the authors observed that both parameters these exhibit a high variability in dependence on the experimental conditions for the same sample. An analysis of the measurements showed that the values obtained follow the Meyer-Neldel rule. In addition, the photoconductivity also appeared to be thermally activated within the investigated temperature range.
