Abstract

In order to characterize CdTe/CdZnTe detectors in a planar configuration, we have developed a new spectral model based on the charge transportation properties in the device. The low mobility-lifetime (μτ) products of carriers in CdTe/CdZnTe detectors produce a position dependency in the charge induction efficiency. The model takes the induction efficiency and interaction positions of photons into account. Since the model is parameterized by μτ products, it can also be used as a new method to extract μτ products. Here, we demonstrate how the model works based on the results from 2 mm thick HPB CdZnTe
