摘要：

Modulation spectroscopy has been applied to several III-V ternary alloys, grown by MBE. Thermal disorder caused by the exciton-LO phonon interaction at room temperature is treated along with alloy disorder in a universal way by assuming a Gaussian absorption profile. A linewidth analysis shows that, in some cases, the presence of inhomogeneous composition variations on a scale of about 7-15 angstrom dominate the spectra. The latter implies that non-random alloys can be grown by MBE.
