Paper Abstract

This paper will introduce a simple model for calculating the quantum efficiency of back- illuminated CCDs. The model incorporates parameters which account for what are believed to be the important features of the back surface: a surface recombination velocity, an electric field which can assist in or oppose the collection of photogenerated carriers and a field free region. Preliminary calculations of device quantum efficiency using the model agree with earlier results and indicate only moderate fields are required to enhance the quantum efficiency especially at short wavelengths.
