Abstract
Our model also shows that the weak dependence on the sample thickness of the absorptivity derived from the photoconductivity spectrum cannot be explained if the surface is schematized as a thin layer different from the bulk only because of a larger defect density. The simulations suggest that this weak dependence could be due to band-bending effects.Keywords
