abstract = {Alloy scattering in a sSi/Si0.5Ge0.5/strained Silicon on
Insulator (SOI) (sSOI) quantum-well (QW) p-MOSFET is
investigated by hole density modulation through applying
back-gate biases. The hole mobility under negative back-gate
biases is found degraded by intensified alloy scattering at
low electrical field because more holes are distributed in
the bulk Si0.5Ge0.5. At higher electrical field, the higher
density of holes populated at the Si/ Si0.5Ge0.5 interface
and less holes in the bulk Si0.5Ge0.5 result in less
pronounced alloy scattering, leading to mobility enhancement
under negative back-gate biases. This confirms
experimentally that alloy scattering does not play a
significant role in the hole mobility of sSi/
Si0.5Ge0.5/sSOI QW p-MOSFETs under normal operating mode.},
