Abstract

The optical characterization technique of photoreflectance (PR) has been modified by replacing the source of the probe light with a dye laser. This has allowed easy access to temperatures below 100K, a temperature range in which it was previously difficult to measure a PR spectrum. This system is also capable of simultaneous photoluminescence excitation spectroscopy (PLE). The combined PR/PLE apparatus has allowed us to obtain information regarding the nature of the PR signal.
