| Abstract: | Two dark-current test methods for or the mercury cadmium telluride(HgCdTe)infrared focal plane detector are studied. Reducing the dark current is directly related to the signal-to-noise ratio of the detector. The dark current of the developed HgCdTe photovoltaic detector under working conditions is tested and analyzed. By comparing multiple test results, it is found that the operating temperature and process have different degrees of influence on the dark current. This study provides a theoretical basis for improving the process, detector performance and screening efficiency in the future. |
