Advanced electrode concepts for CdZnTe radiation detectors


EMSL Project ID
11593a

Abstract

Radiation detector devices manufactured from CdZnTe can be used at ambient temperature. However, spectroscopy using CdZnTe detectors requires some sophisticated approaches to signal generation and/or detection. Furthermore, the electrode-semiconductor interface plays a significant role in the final perfomance of the device. To explore possible improvements to detector performance, we will test new processing steps. These will include the use of controlled oxidation to promote electrode adhesion and minimize interfacial charge trap states and patterned electrodes to allow signal modeling to determine radiation source.
