Studies on vacuum deposited p-ZnTe/n-CdTe heterojunction diodes

Abstract: The present paper reports the fabrication and detailed electrical characterization of p-ZnTe/n-CdTe heterojunction diodes prepared by vacuum deposition method. The possible conduction mechanisms of the heterojunction diode were determined by analyzing the I–V characteristics. The C–V characteristics of the heterojunction diodes were studied to determine the barrier height, carrier concentration and thickness of the depletion region in the heterojunction. A theoretical band diagram of the heterojunction was drawn based on Anderson’s model. [ABSTRACT FROM AUTHOR]
