SBIR Phase I: Hydrogen Passivation of As-Grown Defects in CdZnTe for Improved Gamma Detection

SBIR第一期研究项目是通过氢化过程钝化生长缺陷来提高CdZnTe基伽马射线探测器的性能。这些缺陷是漏电流的一个来源，并导致检测器的背景噪声。这项研究的成功完成将提高伽马射线探测器在从天文学到医学领域的应用中的性能。与具有低缺陷浓度的生长材料相比，钝化是一种低成本的过程。

This SBIR Phase I research project is to improve the performance of CdZnTe based gamma ray detectors by passivating as grown defects through a hydrogenization process. These defects are a source of leakage current and contribute to the backgound noise of the detectors.Successful completion of this research will improve the performance of gamma ray detectors in applications ranging from Astronomy to the medical fields. Passivation is a low cost process compared to growing material with inherently low defect concentrations.
