Optical Properties of Ordered GaInP

Optical Properties of Ordered GaInP

Research output: Contribution to conference › Paper

Abstract

We use the information from low temperature PLE spectra measured on a set of samples with different degree of order for an investigation of the correlation between the order dependent valence band splitting and band gap reduction. The experimental values are compared with predictions from recent ab initio band structure calculations. Moreover, we show how the low temperature optical properties ofordered GaInP2 are related to the microstructure of the material. We find a close correlation between the size of the ordered domains and the relative intensity of the intrinsic PL-peak from excitonic recombination compared with the rapidly shifting, below band-gap luminescence emission.
