Theoretical Investigation Of Performance In Uniaxially- and Biaxially-Strained Si, SiGe and Ge Double-Gate p-MOSFETs

Using the non-local empirical pseudopotential method (bandstructure), full-band Monte-Carlo simulations (transport), 1D Poisson-Schrodinger (electrostatics) and detailed band-to-band-tunneling (BTBT) (including bandstructure and quantum effects) simulations, the effect of uniaxial- and biaxial-strain, band-structure, mobility, effective masses, density of states, channel orientation and high-field transport on the drive current, off-state leakage and switching delay in nano-scale, Si, SiGe and Ge, p-MOS DGFETs is thoroughly and systematically investigated
