Abstract

In this paper, we describe the synthesis and characterization of the solid solution Cu₂Zn_1-xFe_xGeSe₄. Electronic transport data have been analyzed using a single parabolic band model and have been compared to Cu_2+xZn_1-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.
