Abstract

Low temperature diamagnetic shifts and FWHM linewidths of excitonic transitions in Al[sub x]Ga[sub 1-x]As alloys are reported as a function of magnetic field (50T maximum) at 4K using photoluminescence spectroscopy. Two samples with aluminum compositions of 5 and 20%, are discussed. The slope of the diamagnetic shift at high fields allows a direct measure of the excitonic reduced mass μ. [ABSTRACT FROM AUTHOR]
