A strong contribution of the phase separation to the alloy scattering potential is determined for the first time in the composition range from [ital y]=0.4 to [ital y]=1.0 in high-purity Ga[sub [ital x]]In[sub 1[minus][ital x]]As[sub [ital y]]P[sub 1[minus][ital y]] alloys. The composition fluctuation leads to a sharp increase in the alloy scattering potential at [ital y]=0.7, in perfect agreement with yet unexplained experimental electron mobility determinations.
