Observation of the variable-range hopping conduction in amorphous In-Se films

The temperature dependence of the Seebeck coefficient and the electrical conductivity were measured for amorphous In–Se films with compositions around In 40 Se 60 . The variable-range hopping conduction is dominant nearly up to or slightly above room temperature. Above that temperature activation co...

Zusammenfassung:The temperature dependence of the Seebeck coefficient and the electrical conductivity were measured for amorphous In–Se films with compositions around In 40 Se 60 . The variable-range hopping conduction is dominant nearly up to or slightly above room temperature. Above that temperature activation conduction begins by electrons being supplied from donor-like localized states at about 0.4 eV below the conduction band.
