dc.description.abstractThe temperature dependence of dc conductivity of Se85-xTe15Gex (x=0, 2, 6, 10, 15) chalcogenide glasses in the temperature range 273-333 K, has been reported. The dc conductivity varies exponentially with temperature for all compositions. The log σdc versus 1000/T plots are almost straight lines in whole studied temperature range indicating a singly activated phenomenon with single activation energy. Meyer-Neldel rule between pre-exponential factor and activation energy has been observed. Meyer-Neldel characteristic energy (EMN) and σ00 come out to be 40.67 meV and 3.78*10-6 S cm-1, respectively.Both values lie in the range predicted by Shimakawa and Abdul-Waheb for chalcogenide glasses.en_US
