IR Detectors Technology

Abstract

This report results from a contract tasking Charles University as follows: The contractor will perform a series of in-situ Hall effect and conductivity measurement of CdTe/CdZnTe material to determine dependence of temperature above the melting point. A new setup for high temperature galvanomagnetic measurements enabling better control of the Cd overpressure above the melt will be constructed. Based on the experimental and theoretical results a model will be determined and defect concentrations in samples annealed under defined conditions will be further verified, Near perfect (CdZn)Te crystals of diameter up to 10 cm under a defined Cd overpressure will be prepared and evaluated.
