摘要：

Modulated Reflection and Transmition spectra on the InxGa1-xAs/InP system were analysed in terms of alloy disorder and alloy clustering. It has been found that experimental data cannot be understood by considering a completely random alloy. A random distribution of Ga and In atoms in a larger scale 10Å explain better the broadening of the spectra. However, this is in disagreement with the 100Å scale, inhomogeneities observed in these samples by TEM. © 1990.
