Silicon nanowire FET (SiNWFET) with dynamic polarity control has been experimentally demonstrated and has shown large potential in circuit applications. To fully explore its circuit-level opportunities, a physics-based compact model of the polarity-controllable SiNWFET is required. Therefore, in this paper, we extend the solution for conventional SiNWFETs to polarity-controllable SiNWFETs. By solving...
In this paper an analytic channel potential-based model is proposed to predict the dynamic depletion behavior of surrounding-gate (SRG) MOSFETs with arbitrary doping level. The key input voltage equation is derived out by solving Poisson's equation approximately with arbitrary doping in the cylindrical coordinate. Combined with the surface-centric potential relationship, the electrostatic potential...
In this paper an analytic model for Ge/Si core/shell nanowire MOSFETs (NWFETs) is developed. First, the electrostatic potential and charge model are derived out from classical device physics. Then the drift-diffusion drain current model is obtained and verified by comparisons with the numerical simulation. The ballistic current model is obtained with the approximately described quantum-mechanical...
A global continuous channel potential solution is proposed for the modeling of symmetric double-gate (DG) MOSFETs. To obtain the channel potential, from accumulation to inversion regions, 1-D Poissonpsilas equation in the silicon film of the DG MOSFETs is solved physically. The extensive comparisons between the calculated results and numerical simulations illustrate that the analytical solution is...
