Physics-Based Core Compact Model of 2D MoS2 FET Considering Fermi-Dirac Statistics

In this paper, we present a physics-based core compact model for two-dimensional (2D) molybdenum disulfide (MoS
2
) channel material-based FET. The FET characteristics have been studies using ab-initio simulations as well as experimental data. The model is derived from closed-form solutions of Poisson’s equation considering 2D density of states and Fermi-Dirac statistics along with drift-diffusion transport model. The proposed model has been implemented in Verilog-A and validated with ab-initio simulations and experimental data.
