Abstract
In situ ellipsometric characterizations of Si1-xGex alloys are present ed. The samples are grown by chemical beam epitaxy using silane and ge rmane. The growth process (kinetics, composition etc.) is in situ cont rolled using a rotating-polarizer multiwavelength ellipsometer. Severa l examples of heteroepitaxy followed by ellipsometry are shown: desorp tion of the native oxide and the initial growth stages are analysed at different photon energies. The sequential heteroepitaxy of Si0.85Ge0. 15 on Si and Si on Si0.85Ge0.15 is investigated.
