An All-Region I–V Model for 1-D Nanowire MOSFETs

An all-region short-channel MOSFET, model is developed for nanowire semiconductors with 1-D density of states. It is shown that in the quantum capacitance limit, the long-channel saturation current exhibits a (Vgs - Vt)3/2 dependence on gate voltage. With the velocity saturation effect implemented in the model, the Ids-Vgs characteristics of 1-D MOSFETs are compared to those of 2-D MOSFETs at 10-n...
