Transport Properties of Ge Doped As₂Se₃ Glasses

Abstract

The D.C. conductivity, thermoelectric power and photoconductivity have been measured for (As₂Se₃)_100−xGe_x (x=0, 1, 5, 10) glasses. These data were systematically analyzed by the small polaron model. It might be concluded that the doping of Ge does not influence the dark carrier transport processes but remarkably influence the photocarrier one.
