High Magnetic Field Dependent Diamagnetic Shifts in AlxGa1-XAs Semiconductor Alloys
Abstract
Low temperature diamagnetic shifts and FWHM linewidths of excitonic transitions in AlxGa1-xAs 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.
