Resistivity simulation of CZT materials

Journal of Crystal Growth, 1999
Abstract Defects and the relations with the levels introduced in the gap are among the toughest remaining problems in II–VI semiconductors. Up to now, more than 30 levels have been detected without any clear identification and assignation for most of them. PICTS, TEES and TSC are well suited for such investigation, but not complete.

High Efficiency, Spectroscopic CZT Array

MRS Proceedings, 1997
AbstractCompact, efficient, spectroscopic detector arrays which preferably operate without cooling have applications in the fields of x-ray astronomy, nuclear medicine and radioactive materials management. We have fabricated a 16 element CdZnTe detector array that provides a stopping efficiency of greater than 80%, a photopeak fraction of 44% and an ...

Investigation of Zn/Sn ratio for improving the material quality of CZTS thin films with the reduction of Cu2-xS secondary phase

, 2021
In this study, a sputtering system was adopted for the preparation of Cu2ZnSnS4 (CZTS) thin films with high material quality. The system precisely controlled the elemental ratio in a copper-zinc-tin (CZT) precursor for contributing to the grain growth of

System identification for the ECG using CZT

Computers and Biomedical Research, 1992
A new approach for extraction of clinically useful parameters from the ECG signal is presented using the system identification technique of CZT on the DCT-transformed signal. A one to one relationship between the model singularities and the significant points in the time signal is arrived at.

Fano Factor Determination For CZT

MRS Proceedings, 1997
AbstractContinued improvements in the manufacturing of Cd1−xZnxTe (CZT) material have resulted in a practical thermoelectrically cooled X-ray and gamma-ray detector of very high energy resolution. A high resolution spectroscopy system was used to measure the Fano factor in CZT at temperatures down to -40°C.

A retrospective on CZT

Software: Practice and Experience, 2011
AbstractCommunity Z Tools (CZT) is an open‐source Java framework for building formal methods tools for the specification language Z and extensions of Z. This paper gives an overview of CZT: its history, architecture, and development process. Extensibility is core to CZT and the main aims of this paper are to encourage and enable formal methods tool ...

Double-Layered CZT Compton Imager

IEEE Transactions on Nuclear Science, 2017
In this paper, we propose a double-layered cadmium zinc telluride Compton camera using the weighted list-mode maximum likelihood expectation maximization (MLEM) method. We performed a Monte Carlo simulation of the performance. The detection system comprised two detector arrays arranged in parallel.

Properties of thermally evaporated CZTS thin films and numerical simulation of earth abundant and non toxic CZTS/Zn(S,O) based solar cells

, 2020
Earth abundant Cu2ZnSnS4 (CZTS) films were grown by thermal evaporation technique onto non heated substrates. As deposited CZTS films were annealed under two different atmospheres: (1) vaccum annealing atmosphere and (2) sulfur annealing atmosphere ...
