dc.description.abstractRigorous quantum mechanical transport calculations based on the multi-band k . p Hamiltonian are performed in this work to show that the coupling of heavy and light holes (LHs) greatly reduces on-state hole current in ultra-scaled p-type Si nanowire FETs. If the coupling between the heavy and light holes is artificially suppressed, on-current of the p-type devices almost doubles and becomes comparable to that of n-type counterparts. It is found that the effect of the coupling on the hole transport is maximized at the channel width of around 5 nm. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3644959]-
