Popis: Rapid thermal oxidation (RTO) of the Ge-rich (x=0.7)Si1−xGex heterolayer is reported. In particular, the structural modifications of SiGe films during oxidation process and the dependence of the oxidation kinetics on Ge content, oxidation temperature, and oxide thickness have been studied. The segregation mechanism of Ge at the oxide∕SiGe interface is discussed. Interface properties of the RTO-grown oxides studied using high-frequency capacitance-voltage (C-V) characteristics of metal-oxide-semiconductor capacitors are also reported.
