Logic Computing Field-Effect Transistors Based on a Monolayer WSe₂ Homojunction for the Semi-adder and Decoder

Two-dimensional reconfigurable field-effect transistors (FETs) are promising candidates for next-generation computing hardware. However, exploring the cascade design of FETs for logic computing remains challenging. Here, by using density functional theory combined with the nonequilibrium Green's function method, we design a 5 nm split-gate FET based on a monolayer WSe
