Abstract
A new analytical model for the surface potential and threshold voltage of a surrounding-gate MOSFET with dual-material gate is presented to investigate the short-channel effects. The model results accurately predict the threshold-voltage "roll off" for channel lengths even less than 90nm. The accuracy of the model results is verified using two-dimensional simulation.
