DIAZ ALBARRAN, S.F; ELYUKHIN, V.A; RODRIGUEZ PERALTA, P  and  GONZALEZ NOGUEZ, A.G. On the spinodal decomposition of In_xGa_1-xN_yAs_1-y and GaSb_xN_yAs_1-x-y alloys. Rev. mex. fis. [online]. 2008, vol.54, n.1, pp.25-29. ISSN 0035-001X.

Spinodal decomposition ranges of GaAs-enriched GaSb_xN_yAs_1-x-y and In_xGa_1-xN_yAs_1-y quaternary alloys as the result of the transformations of the bonds, strain and coherency strain energies at the phase separation are described. The alloys are represented as strictly regular solutions. The spinodal decomposition ranges of the alloys are demonstrated up to 600°C. It is shown that GaSb_xN_yAs_1-x-y alloys having one mixed sublattice are more promising from the standpoint of spinodal decomposition than In_xGa_1-xN_yAs_1-y alloys with two mixed sublattices.
