Time response of Cd0.9Zn0.1Te crystals under transient and pulsed irradiation

AIP Advances, 2012
A CdZnTe detector based on high-quality Cd0.9Zn0.1Te crystals was developed and tested as a monitor in high-intensity radiation fields. The current–voltage measurements were performed using thermally evaporated Au contacts deposited on the crystals ...

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.

Use of bremsstrahlung radiation to identify hidden weak beta- sources: feasibility and possible use in radio-guided surgery

, 2017
The recent interest in beta- radionuclides for radio-guided surgery derives from the feature of the beta radiation to release energy in few millimeters of tissue.

High spectral resolution of gamma-rays at room temperature by perovskite CsPbBr3 single crystals

Nature Communications, 2018
Detection and spectroscopic measurements of gamma-ray used to rely on expensive materials such as CdZnTe crystals. Here He et al. develop a melt method to grow large size CsPbBr3 perovskite crystals and the devices achieve low cost, high energy resolving
