WSURF Case 829
Cadmium Zinc Telluride (CZT)
Summary:
Cadmium Zinc Telluride (CZT) has emerged as the detector material of choice for imaging applications because it works at room temperature with excellent energy resolution and has a large atomic number (Z). A major impediment to a more widespread implementation of these materials derives from the difficulty associated with reliable and repeatable synthesis of CZT materials. Even under the most controlled conditions, low yields are ubiquitous. Researchers at Washington StateUniversity have produced a new CTZ-based detector material providing many desirable attributes:
Applications & Advantages
- Novel Doping Combination; Unique from other patent protected combinations
- Consistently provides high yields of active materials (resistivities on the order of ~1010 W cm and (µt)e of ~10-3cm2/V)
- ~2% FWHM at 662keV
- Large range of effective dopant concentrations
- Growth times as short as 10 days
IP Status
The technology is protected by a provisional US Patent and is available for exclusive licensing worldwide.
