Paper Abstract

0.1eV HgCdTe photoconductive detectors with optical masks have been developed to improve spatial resolution and sensitivity. Measurements on carrier lifetime, responsivity and noise were made for the newly developed detectors as well as ordinary ones. The following results were obtained. (1) Measured responsivity for the new detectors was 2-3 times as high as that for the ordinary ones. (2) NEP for the new detectors showed better performance in wide bias current range. Finally, calculations on carrier lifetime, responsivity and noise were carried out by solving a 3-dim. transport equation. The calculated values agreed well with the measurements.
