Physics-based compact model for circuit simulations of 2-dimensional semiconductor devices

Anticipating a push towards circuit applications of field-effect transistors (FETs) with two-dimensional (2D) semiconductors like MoS₂, there is a growing need to evaluate such devices at a circuit level. However, early 2D FET models have been either too idealistic or did not address circuit simulation. Here we describe the first SPICE-compatible compact model for realistic simulation of 2D FETs in circuits. The semi-classical model has been developed in Verilog-A and an initial version is available online. In addition to physical rigor, the model has been extensively calibrated against state-of-the-art experimental devices both from our lab and the published literature.
