  • Abstract
    A thin (~20 nm) compressively-strained selective epitaxially grown Ge film was grown on small Si active areas by ultra-high vacuum-chemical vapour deposition. The Ge PMOSFETs with HfO2 gate dielectric show a ~2 x drive current enhancement and greater than 2 x improvement in hole mobility compared to control Si PMOSFETs.
