A scheme for spin transistor with extremely large on/off current ratio

Year: 2008

Type: article

Abstract: Quantum wires with periodic local Rashba spin-orbit couplings are proposed for a higher performance of spin field-effect transistor. Fano–Rashba quantum interference due to the spin-dependent modulated structure gives rise to a broad energy range of vanishingly small transmission. Tuning Rashba spin-orbit couplings can provide the on or off currents with extremely large on/off current ratios even in the presence of a strong disorder.
