Room-temperature carrier transport in high-performance short-channel Silicon nanowire MOSFETs

Room-temperature carrier transport in Si nanowire (NW) MOSFETs with gate lengths and diameters down to 25 and 8 nm, respectively, is analyzed. It is shown that in Si NWs, holes exhibit channel injection and thermal velocities, as high as the highest obtained for uniaxially strained planar Si-channel electrons, likely due to combination of strain and confinement.
