摘要
Internal photoemission and photoconductivity experiments are used to characterize interfaces of high-mobility semiconductors GaAs, InxGa1-xAs, Ge, and Si1-xGex with metal oxide insulators. Compared to silicon, formation of a narrow-gap interlayer and composition-sensitive semiconductor band structure are revealed as the most influential factors affecting the interface barriers.
