Abstract

In this paper we critique the first order quantum efficiency and modulation transfer function (MTF) analysis for photocollection in both a finite and semi-infinite slab of semiconducting material. We derive the correct equations from first principles and perform a case study comparing photodetection in silicon and GaAs. This is of interest in the first order design of GaAs and silicon optical smart sensors and solid-state imagers.
