Effect of Te precipitates on the performance of CdZnTe detectors
Gabriella Carini,Aleksey E. Bolotnikov,Giuseppe S. Camarda,Gomez W. Wright,Ralph B. James,L. Li +5 more
TL;DR: In this article, a detailed comparison of the microscale detector response and infrared microscopy images for CdZnTe Frisch-ring x-ray and gamma detectors is presented.
Cumulative effects of Te precipitates in CdZnTe radiation detectors
Aleksey E. Bolotnikov,Giuseppe S. Camarda,Gabriella Carini,Yonggang Cui,L. Li,Ralph B. James +5 more
TL;DR: In this article, the effects of small-size Te precipitates on charge collection in CZT detectors were investigated and a simplified model based on the geometrical aspects of the problem was developed.

TL;DR: In this paper, the effects of small, < 20 mum, Te inclusions on the energy resolution of CdZnTe gamma-ray detectors using a highly collimated X-ray beam and gamma-rays, and modeled them via a simplified geometrical approach.
Modelling the effects of Te precipitates on the electron transport in CdZnTe radiation detectors
Aleksey E. Bolotnikov,Giuseppe S. Camarda,Gabriella Carini,Yonggang Cui,L. Li,Ralph B. James +5 more
TL;DR: In this article, the performance of CdZnTe (CZT) nuclear-radiation detectors was evaluated with high-spatial resolution, and it was shown that randomly distributed small Te precipitates are not harmful.

Performance studies of CdZnTe detector by using a pulse shape analysis
Aleksey E. Bolotnikov,Giuseppe S. Camarda,Gabriella Carini,Michael Fiederle,L. Li,Gomez W. Wright,Ralph B. James +6 more
TL;DR: Pulse shape analysis is proved to be a powerful tool to characterize the performance of CdZnTe devices and understand their operating principles as discussed by the authors, which allows one to investigate the device configurations, electron transport properties, effects governing charge collection, electric-field distributions, signal charge formation, etc.
