Abstract: Structures based on Indium Gallium Arsenide (InGaAs) have attracted a lot of interest in Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) technology recently. In this paper, a new nano-scale dual-gate MOSFET using In0.75 Ga0.25As is proposed. Multiple designs were simulated with different doping concentration in the source/drain region and the channel stop region to get an excellent Ion/Ioff. Since current in Metal-Oxide-Semiconductor (MOS) depends on the doping profile of the channel, a careful re-engineering of the channel would improve the MOSFET characteristics. Channel length, Lg of the proposed device is 20 nm which produces a significant amplification and supports large current due to wide channel interaction. Simulation of In0.75 Ga0.25 As MOSFET with Lg = 20 nm, gate-oxide thickness toxGate1 = toxGate2 = 2nm and a width Z = 1000nm, exhibits transconductance gm-max ? 293.626 ?S/?m, subthreshold slope SS ? 70 mV/decade and drain-induced-barrier-lowering DIBL = 41.66 mV/V. � 2017 IEEE.
