Raman line-shape analysis of random and spontaneously ordered GaInP[sub 2] alloy

We have measured the temperature dependence of the Raman frequency and linewidth of the GaP-like LO phonon of random and spontaneously ordered GaInP[sub 2] alloys. The width of the asymmetric Raman band is strongly influenced by disorder and the anharmonicity of the lattice. The half-width towards t...
