Spectral supralinearity of silicon photodiodes in visible light due to surface recombination

摘要

Spectral supralinearity of silicon photodiodes in visible light was investigated. The experimental spectral supralinearity results were compared with the calculation results using a device simulator, PC1D that includes the front surface recombination parameters, and these comparison results were in reasonable agreement for a silicon photodiode. These comparison results show that supralinearity in visible light clearly occurs with a front surface charge density of more than 10(12) cm(-2) and the included parameters are adequate for quantitatively predicting the internal quantum efficiency of silicon photodiodes.
