Abstract
We have studied the asymmetric broadening of the Raman spectra of In G a1-xAsyP1-y grown on GaAs substrates by means of the spatial correlati on model. The broadening phenomena was found to be enhanced in the reg ion of immiscibility, in agreement with PL observations. In Raman meas urements, the broadening is more enhanced in the samples grown on (100 ) substrates than in the samples grown on (111) substrates. The enhanc ement is attributed to the immiscibility included in the samples grown on (100) substrate.
