摘要
Abstract
In the paper, theory of calculation of quantum efficiency is analyzed first, then photovoltaic (PV) detectors are fabricated with medium wave (MW) InAs/GaSb typeⅡ super lattice is analyzed. Based on the test results of electrical parameters and spectral response of the photodiode, actual current responsivity is calculated. Then the actual current responsivity is divided by theoretical current responsivity, and the influence of optical transmittance of SiO2 passivation layer is considered simultaneously, so the quantum efficiency of InAs/GaSb typeⅡ super lattice photodiode can be obtained. The peak quantum efficiency of photodiode can reach up to 35% between 2?m and 6?m, which is comparative to the results of photodiodes abroad with the similar type. The research provides an effective method to evaluate the photoelectric conversion performance of InAs/GaSb typeⅡ superlattice detectors objectively.关键词
