Empirical Pseudo-Potential Calculations in GaAs1—xNx and AlAs1—xNx Ordered Alloys
Abstract
We have performed an empirical pseudo-potential study of the fundamental excitation in ordered alloys of III–V semiconductors GaAs1—xNx and AlAs1—xNx. Various quantities including the bowing parameters of the fundamental gaps, the energy levels, the charge densities, the ionicity character, the refractive index and the transverse effective charge are calculated.
