Investigation of nanowire size dependency on TSNWFET
ABSTRACT Nanowire size (dNW) dependency of various electrical characteristics on gate all around twin silicon nanowire MOSFET (TSNWFET) is investigated to understand overall performance of nanowire transistor deeply. When dNW decreases, current drivability (Ion) normalized by circumference at the same VG-VTH improves and maximizes at dNW of 4 nm. And mobility is also estimated with capacitance and series resistance. All the experimental investigation shows that dNW of 4 nm is the best point to maximize the volume inversion effect on gate all around nanowire MOSFET.
