Effect of copper on DC and AC conductivities of (As 2Se 3)–(AsI 3) glassy semiconductors

The work is concerned with the effect of copper content on electrical conductivity of the bulk amorphous semiconducting glasses from the system Cu x [(As 2Se 3) 0.9(AsI 3) 0.1] 100 − x ( x = 0, 1, 5 and 10 at.% Cu). The DC conductivity, measured in the temperature range of 300–420 K, shows a semicon...
