Realization and Characterization of CZT X-Ray and gamma ray detectors

Radiation detection is a very important tool for every application field that includes monitoring and detection of radiation sources. In the case of gamma and X-ray detectors, a wide number of application fields are involved in the detector developing, this list comprehends medical imaging, environmental monitoring, homeland security and astrophysics. In recent years CdZnTe(CZT) has emerged as an interesting material for the realization of room temperature X- and gamma ray detectors. In this work IMEM grown CZT ingots and detectors were studied with several techniques, in order to understand the mechanisms occurring in the device functioning. The results were pushed together to create a direct feedback with the crystal growers of the group.
