Spinodal decomposition ranges of Inx Ga1-x Ny P1-y and GaAsx Ny P1-x-y alloys
We have described spinodal decomposition ranges of GaP-rich GaAsxNyP1¡x¡y and InxGa1¡xNyP1¡y alloy lattices matched to the GaP (001) substrate up to temperatures of 600±C. Transformation of bonds, strain and coherency strain energies at the phase separation are taken into account. The alloys are con...

| Sumario: | We have described spinodal decomposition ranges of GaP-rich GaAsxNyP1¡x¡y and InxGa1¡xNyP1¡y alloy lattices matched to the GaP (001) substrate up to temperatures of 600±C. Transformation of bonds, strain and coherency strain energies at the phase separation are taken into account. The alloys are considered to be strictly regular solutions. The strain energies of the alloys were calculated with the interaction parameters estimated by the valence force field model. It is shown that GaAsxNyP1¡x¡y, having one mixed sublattice, are more promising from the spinodal decomposition standpoint than InxGa1¡xNyP1¡y, with two mixed sublattices. |
