As MOSFETs are scaled to deep submicron dimensions non-equilibrium, near ballistic, transport in p-MOSFETs becomes important. Recent experimental data indicates that as MOSFETs are scaled the performance gap between n and p-channel shrinks. Nonequilibrium transport effects and performance potentials of ‘Well Tempered’ Si p- MOSFETs with gate lengths of 50 and 25 nm are studied. Monte Carlo and calibrated Drift Diffusion simulations of these devices provide a quantitative estimate of the importance and the influence of non-equilibrium transport on submicron device performance. A possible explanation for the closing performance gap between n- and p-channel MOSFETs is offered.

This paper describes analysis and simulations of Si and III-V Gate-All-Around nanowire MOSFETS assuming ballistic or quasi-ballistic transport. It is found that either channel material can provide the higher saturation current depending on the oxide thickness. For effective oxide thickness above approximately 0.5nm, the higher electron velocity of III-V's outweighs the higher density of states available in the Si device associated with higher effective mass and valley degeneracy and result in higher current for the III-V device. However, materials with higher effective mass and valley degeneracy result in smaller on-resistance in ballistic limit. Depending on the gate oxide capacitance, valley degeneracy may influence the attainable saturation current in a positive or negative way.
