CDTE AND CDZNTE PIXEL DETECTORS FOR X-RAY SPECTROSCOPIC IMAGING

, 2012
Cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) wide band gap semiconductors for x-ray detectors have experienced a rather rapid development in the last few years. Among the traditional x-ray detectors based on silicon (Si) and germanium (Ge)

Enhancement of Resistivity of CdZnTe Crystal by Laser Radiation

In this paper we present a study on the enhancement of CdZnTe crystal resistivity by λ=1064nm Nd:YAG laser radiation. This effect is explained by compensation of cadmium vacancies (VCd) by indium atoms due to a laser-induced temperature gradient around ...

Characterization of CdZnTe semiconductor for applications in advanced computed tomography [PDF]

, 2017
Cadmium zinc telluride (CdZnTe) is currently the only single crystalline semiconductor used in direct conversion gamma-cameras since CdZnTe can operate at room temperature, unlike other materials (e.g., germanium) that require liquid nitrogen cooling.

Laser Ablation in CdZnTe Crystal due to Thermal Self-Focusing: Secondary Phase Hydrodynamic Expansion

The present paper deals with the laser ablation in CdZnTe crystal irradiated by pulsed infrared laser. Two values of threshold intensities of the laser ablation were determined, namely of about 8.5 and 6.2 MW/cm2 for the incident and the rear surfaces ...

Chargеs collection efficiency in gamma-ray detectors with different electrodes configuration

Технологія та конструювання в електронній апаратурі, 2012
The dependence of the charge collection efficiency n in gamma-ray detectors based on CdZnTe on the impurity composition of the material has been investigated. Plane-parallel, cylindrical and spherical electrodes have been considered.
