| Abstract Scope |
Gamma radiation detectors are heavily utilized in nuclear industry today, from security and safety to fundamental physics, many insights can be gained from being able to record the gamma radiation signal emitted during nuclear processes. Cadmium zinc telluride (CZT) is a material of choice for room-temperature gamma radiation detection owing to its low-background and good electron-transport properties. The primary barrier to widespread utilization of CZT over older, conventional detectors is its high cost. WSU has been working on an alternate growth method for the low-cost production of CZT, namely Accelerated Crucible Rotation Technique (ACRT). Recently, WSU has been successful in obtaining high-quality CZT (~1.5% FWHM @ 662keV) at 10x the growth rate of THM using the ACRT method and is further optimizing the growth process to improve the single-crystal yield. A balance must be struck between single-crystal yield and the electrical properties of the CZT (stoichiometry adjustments). |
