摘要

We demonstrate enhancement of electron mobility in nMOSFET using an ultrathin pure Ge crystal channel layer directly grown on a bulk Si wafer. A thin Si crystal layer is also grown on top of a Ge crystal channel layer as a capping layer. Using the Si/Ge/Si structure, a maximum 2.2X enhancement in electron mobility is achieved while good gate dielectric properties and junction qualities of bulk Si devices are maintained.
