Performance simulation of nanoscale silicon rod field-effect transistor logic

We have simulated the behavior of a rod shaped nanoscale ring-gated field-effect transistor (RG-FET) using the PISCES-IIb semiconductor drift-diffusion solver. The results from these simulations are used by a customized SPICE 3f5 kernel to simulate several simple logic gates. The usefulness of this kind of transistor is examined within the context of a self-assembling fabrication technique that we outline.
