Monte Carlo Simulation of Spin Polarized Transport in Nanowires and 2-D Channels of III-V Semiconductors

摘要

We simulated spin polarized transport of electrons along III-V nanowires and two dimensional III-V channels using semi classical Monte Carlo method. Properties of spin relaxation length have been investigated in different III-V zinc-blende materials at various conditions, such as, temperature, external field etc. Spin dephasing in III-V channels is caused due to D'yakonov-Perel (DP) relaxation and due to Elliott-Yafet (EY) relaxation. Spin dephasing length in nanowire is found to be greater than that in 2-D channel.
