  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.
