Simulation study of the 20nm gate-length Ge implant-free quantum well p-MOSFET

In this paper a drift diffusion simulation study of a 20nm gate-length implant-free quantum well germanium p-MOSFET is presented, which covers the impact of mobility, velocity saturation and density of interface states on the transistor performance. The parasitic gate capacitance was also studied. The simulations show that the 20nm gate-length implant-free quantum-well transistor design has good electrostatic integrity and performance potential.
