Abstract

The optical transitions in InGaAsN/GaAs quantum wells were studied. It was observed by low-temperature transmittance and room-temperature photoreflectance spectroscopy that the unstrained valence band alignment was independent of nitrogen fraction. Nitrogen incorporation caused the increase in effective mass and conductance band offset. Lowered compressive strain in the wells caused the variation of the valence band alignment. Results were described by the formalism of the band anticrossing model.
