Abstract

Systematic photoluminescence measurements on a series of ^GaBixAs1_-x samples are analyzed theoretically using a fully microscopic approach. Based on ^sp3s tight-binding calculations, an effective k·p model is set up and used to compute the band structure and dipole matrix elements for the experimentally investigated samples. With this input, the photoluminescence spectra are calculated using a systematic microscopic approach based on the semiconductor luminescence equations. The detailed theory-experiment comparison allows us to quantitatively characterize the experimental structures and to extract important sample parameters.
