TL;DR: In this paper, dc conductivity measurements at high electric fields in vacuum evaporated thin films of amorphous Se80−xTe20Cdx (x = 0, 5, 10, 15) systems have been measured at various fixed temperatures.

TL;DR: In this article, temperature dependence of dark conductivity and photoconductivity has been studied in amorphous thin films of Se 85 Te 15 − ǫ x Pb x (2.5 × ) and deep localized states, which behave like trapping centers, may play an important role in conduction processes at low temperatures.
