摘要

We report on 2D numerical simulations of photoresponse characteristic for long-wavelength HgCdTe infrared photodiodes. Effects of thickness of absorption layer on the photoresponse have been investigated. Optimal thickness of absorption layers at different absorption lengths and diffusion lengths are extracted numerically. An empirical formula is proposed to predict reasonable optimal thickness of absorption layer by theoretically analyzing its correlations with absorption lengths and diffusion lengths.
