Unstable states of BGaN(P, As) / Ga(P, As) materials

The spinodal decomposition ranges of low N-content B x Ga 1-x N y (P,As) 1-y /Ga(P,As) alloys grown on Ga(P,As) (001) substrates, are described. The alloys are represented as strictly regular solutions. In the analysis, we take into account the transformation of the bonds, strain and elastic energie...

Description
Summary:The spinodal decomposition ranges of low N-content B x Ga 1-x N y (P,As) 1-y /Ga(P,As) alloys grown on Ga(P,As) (001) substrates, are described. The alloys are represented as strictly regular solutions. In the analysis, we take into account the transformation of the bonds, strain and elastic energies. Spinodal decomposition ranges of B x Ga 1-x N y P 1-y alloys with compositions x = 0.01, 0.013, 0.015 and 0 ≤ y ≤ 0.08 are demonstrated up to 1100°C, and to B x Ga 1-x N y As 1-y with compositions x = 0.008, 0.01, 0.011, 0.012 and 0 ≤ y ≤ 0.06 are demonstrated up to 1180°C. The estimations show that the decomposition ranges are larger when the transformation of the bonds is not considered.
