Abstract | ||||
The electrical conductivity in Se70 Te30-x Inx (0<x<10) at. % exhibited an exponential thermally activated behavior with single conduction mechanism for bulk and thin films. Film conductivities were found to be about three orders of magnitude lower than those of their bulk counterparts bulk samples. An obvious decrease in the conductivity on incorporation of indium to the binary Se70Te30-x film was observed. An experimental correlation between the activation energy and the pre-exponential factor was observed indicating the validity of Meyer-Neldel rule in the studied samples. Huge difference in σ0 values was obtained and hence σ0 may not directly related to the microscopic conductivity. | ||||
