摘要：
The characteristics of the Au contacts deposited by three different processes before and after accelerating aging tests have been investigated in this paper. The experimental results indicate that the aging tests can cause the degradation of the contact interfacial properties, such as continuities, adhesion strength and ohmic characteristics, especially for the contact electrode deposited by the thermal vacuum evaporation, which would influence the performance of CdZnTe detectors.
