Abstract :
We have investigated carrier transport properties in ultra-thin body (UTB) Ge-on-Insulator (GeOI) MOSFETs for the first time. Both n- and p-channel MOSFET operation fabricated on 9 nm GeOI has been demonstrated. In addition, a significant difference of Ge crystallinity in the front-channel from that in back-one is reported to explain the mobility degradation in UTB region.
