Investigation of the Small Pixel Effect in CdZnTe Detectors (.pdf)

Matthew D. Wilson, Paul Seller, Member, IEEE, Matthew C. Veale & Paul J. Sellin, Member, IEEE

Abstract – The signal shapes produced by alpha and X-ray radiation in 2mm thick CdZnTe detectors have been measured. The signals produced in a single large pad detector and a 300μm pixilated detector have been compared. The influence of the small pixel effect and it’s variation with detector bias is visible. Synopsys Sentaurus TCAD is used to simulate the charge carrier motion in the detectors and is compared against the measured signals. A description of how the simulations will aid detector design with optimal pixel size, inter-pixel spacing and bias voltage is included.
