A 3D Quantum Simulation of Silicon Nanowire Field-Effect Transistors

As the device size of the conventional planar metal oxide semiconductor field effect transistor (MOSFET) shrinks into the deep sub micron regime, the device performance significantly degrades mainly due to the short-channel effect. The silicon nanowire field-effect transistor (SNWFET) is considered as an attractive alternative to the planar MOSFET, because its enhanced gate control offers many advantages. In this work, the device characteristics of SNWFET have been investigated by solving the three-dimensional (3D) Poisson equation and the quantum ballistic transport equation self-consistently, and the dependence of the device performance on the gate number, configuration, and shape has been examined in conjunction with the effect of the wave function confinement. Numerical techniques to efficiently solve the 3D problem will be also addressed in this talk.
