Abstract

In this paper we study the electronic properties of amorphous films of As40S30Se30 modified Bi at. %. We determined the temperature dependence of conductivity, conductivity at room temperature, the activation energy of conductivity and optical band gap. After modifying the electronic parameters of Bi films vary considerably depending on the concentration.
