Abstract

Bandgap energy and conduction band offset of pseudomorphic GaAsSb on GaAs are studied by temperature dependent photoluminescence and theoretical model fitting. GaAs0.643Sb0.357/GaAs quantum well is determined to have a weak type-I (almost flat) conduction band alignment over the entire temperature range, with a conduction band offset of 4.5 ± 11.9 meV at 0 K and 11.5 ± 12.6 meV at room temperature.
