Abstract :
InGaAsSb layers were grown on GaSb substrates by liquid phase epitaxy. The variation of the bandgap with composition was determined and a new value for the bandgap bowing parameter is proposed. Mechanisms of the current conduction process in Au/InGaAsSb Schottky barrier structures were determined as well as the value of the Schottky barrier heights.
