Study of Surface Treatment Effects on the Metal-CdZnTe Interface

摘要

In this work it has been investigated the influence of different surface treatments on the electrical properties of the metal-CdZnTe interface. The study was performed on Cd0.9Zn0.1Te grown by Boron Oxide Encapsulated Vertical Bridgman technique. Samples of nearly 7mm x 7mm x 1.5mm were cut out of the grown ingots. Contacts were prepared using different procedures and current-voltage characteristics were recorded to monitor the effect of different surface treatments on the electrical characteristics of the device.
