碲镉汞雪崩焦平面器件
HgCdTe avalanche photodiode FPA
摘要
碲镉汞雪崩光电二极管以其高增益、高灵敏度和高速探测的优点成为第 3代红外光电探测器的重要发展方向之一.制备了截止波长 3. 56 μm的雪崩光电二极管焦平面器件,面阵规模为 16×16.焦平面器件在 0~6 V偏压下有效像元率大于 90%,非均匀性小于 20%. 6 V偏压下 NEPh约为 60,过剩噪声因子为 1. 2.
Abstract
HgCdTe APDis one ofthe developingtrends ofthirdgeneration inferredFPAdetectors. In this paper. we report the result on a16×16 arrays ofHgCdTe avalanche photodiode with3.56 μmcut-off wavelength. The operability in gain exceeds 90% and relative gain dispersion is lower than 20%. NEPh is about 60 at 6 V bias with excess noise factor closeto 1.2.
