A new two-dimensional subthreshold behavior model for the short-channel asymmetrical dual-material double-gate (ADMDG) MOSFET’s

Based on the exact solution of two-dimensional Poisson’s equation, a novel subthreshold behavior model comprising channel potential, subthreshold swing, and threshold voltage for the short-channel asymmetrical dual-material double-gate (ADMDG) MOSFET’s have been developed. The model is verified by its simulation results that agree well with those of the two-dimensional numerical simulator. Besides offering the physical insight into device physics, the model provides the basic designing guidance for the ADMDG MOSFET’s.
