  • Abstract
    We investigate the effect of interface states at the channel/insulator interface of III-V MOSFETs by means of accurate Schrödinger-Poisson and Multi-subband Monte Carlo simulations. Traps in the conduction band are found to be the main responsible of the Fermi level pinning observed in the experiments. These traps impact the mobility measurements as well as the current drive of short channel devices.
