Abstract:

"Cadmium zinc telluride is the room temperature detector of choice for non-destructive imaging applications. Monolithic CZT arrays with high count-rate capability (>1e+6 cps/pixel) are required for ultra-fast hyperspectral x-ray imaging. Presently, theyield of CZT detector arrays that can perform hyperspectral imaging (in milliseconds) is low. Most monolithic arrays suffer from "polarization" when exposed to high flux levels (>1e+6 cps/mm2). Polarization is observed as leveling off or reduction in thecount-rate when the incident flux is increased beyond a certain level. The goal of the Phase II project is to explore in detail the underlying cause(s) for polarization in CZT detectors at high count-rates, and develop methodology to overcome thepolarization effects. The Phase II research will be focused on investigation of issues such as bulk properties, device structure, and device processing. Extensive device simulations and modeling will be conducted towards achieving the desired goal."
