Abstract

Abstract Semiclassical Monte Carlo simulation is used to determine the effect of microscopic ripples on spin relaxation length in freely suspended single-layer graphene. Spin relaxation lengths are simulated using D’yakonov–Perel mechanisms, with comparisons made by including ripple scattering mechanisms along with phonon scattering. The results are simulated with varying temperatures and concentration.
