Abstract
We describe a simple Green’s functionmodel of interface mixing in quantum wells that provides exact quantitative solutions for real structures. Examples are given of several important low‐dimensional heterostructures. The model enables the energy of the band‐edge optical transition to be predicted as mixing proceeds, so that optical characterization techniques such as photoluminescence or absorption provide a powerful tool for studying mixing and obtaining interdiffusion constants.Keywords
