摘要: Full-band ballistic quantum transport calculations were used to study the screening effects in ultrashort-channel few-layer MoS2 transistors. A large density of states resulted small lengths while inhibiting direct source-to-drain tunneling. Short-channel observed even for structurally confined 2-D transistors resulting degraded electrostatic control. Electron confinement also OFF-state multilayered devices.
