Impact of Si cap, strain and temperature on the hole mobility of (s)Si/sSiGe/(s)SOI quantum-well p-MOSFETs
We investigated several effects on hole mobility of quantum-well p-MOSFETs. The Si cap layer improves the hole mobility by suppressing the scattering. High strain in SiGe reduces hole mobilities as enhancing the Ge interdiffusion. Hole mobility is dominated by Coulomb scattering at low temperatures.
