Abstract

A comparison of the electrical transport properties of amorphous and crystalline Ge films codeposited with Al and Cu is presented. The properties of amorphous Ge-metal films are consistent with the formation of homogeneous alloys and the impurity states introduced on alloying. On the other hand, in crystalline Ge-metal films, formation of alloys and/or heterogeneous Ge-segregated metal/compound phases at high metal concentrations explains the observed electrical properties.
