Self-consistent simulation of Schottky Barrier SpinFET

In this paper, we proposed a self-consistent simulator based on Monte Carlo method for performance simulation of SpinFET. In SpinFET, the dominant spin dephasing mechanism is the so called DP(Dpsilayakonov-Perelpsila) mechanism, including Dresselhaus effect and Rashba effect. These effects are closely related to the 2-dimensional electron gas (2DEG) in the channel, especially to its envelop function. Considering this, we introduced self-consistent Poisson-Schrodinger solver into our simulator to obtain 2DEGpsilas envelop wave function and precise spin precession frequency. Using the simulator, we investigated the SpinFET performance dependence on spin injection directions, channel materials and source/drain materials. Based on our simulation results, we proposed some design guidelines for SpinFET.
