Abstract

Comprehending the current-voltage properties of CdZnTe device is an essential step toward improving its spectroscopic performance. Thus an in-depth analysis of I-V characteristics on Au/Cd0.9Zn0.1Te/Au device is carried out in this work. Typical non-linear transitions observed in I-V curve are found to be closely correlated with deep donor in CdZnTe. Profile of deep donor ionization probability is calculated under various biases. Afterwards the distribution of space charge and electric field is obtained. Based on these results, reasons for transitions in I-V curve are revealed. Also, related carrier transport mechanisms are confirmed.
