Abstract

In this paper, we describe the synthesis and characterization of the solid solution Cu2Zn1-xFexGeSe4. Electronic transport data have been analyzed using a single parabolic band model and have been compared to Cu2+xZn1-xGeSe4. The effective mass of these undoped, intrinsically hole conducting materials increases linearly with increasing carrier concentration, showing a non-parabolic transport behavior within the valence band.
