Dynamics of native oxide growth on CdTe and CdZnTe X-ray and gamma-ray detectors

Science and Technology of Advanced Materials, 2016
We studied the growth of the surface oxide layer on four different CdTe and CdZnTe X-ray and gamma-ray detector-grade samples using spectroscopic ellipsometry. We observed gradual oxidization of CdTe and CdZnTe after chemical etching in bromine solutions.
