With technology invading nanometer regime performance of the Metal-Oxide-semiconductor Field Effect Transistor is largely hampered by short channel effects. Most of the simulation tools available do not include short channel effects and quantum effects in the analysis which raises doubt
on their authenticity. Although researchers have tried to provide an alternative in the form of tunnel field-effect transistors, junction-less transistors, etc. but they all suffer from their own set of problems. Therefore, Metal-Oxide-Semiconductor Field-Effect Transistor remains the backbone
of the VLSI industry. This work is dedicated to the design and study of the novel tub-type Metal-Oxide-Semiconductor Field-Effect Transistor. For simulation Non-Equilibrium Green’s Function is used as the primary model of simulation. The device is analyzed under different physical variations
like work function, permittivity, and interface trap charge. This work uses Silicon-Molybdenum Disulphide heterojunction and Silicon-Tungsten Disulphide heterojunction as channel material. Results for both the heterojunctions are compared. It was analyzed that Silicon-Molybdenum Disulphide
heterojunction provides better linearity and Silicon-Tungsten Disulphide heterojunction provides better switching speed than conventional Metal-Oxide-Semiconductor Field-Effect Transistor.
