Abstract

The dependence of the band gap (E _G) and higher critical-point energies of dilute-nitrogen Ga _1-yIn _yAs _1-xN _x epilayers on nitrogen mole fraction (x) was investigated using photoreflectance spectroscopy. It was found that band gap decreases with increasing x in a highly nonlinear fashion. It was observed that as x increases, the bowing parameter become less negative. Results suggest that nitrogen-related impurity levels arise within the band gap of dilute-nitrogen GaInAsN alloys.
