Abstract

Spin precession and dephasing (``Hanle effect'') provides an umbiguous means to establish the presence of spin transport in semiconductors. Analytic spin precession simulator simulates ``Hanle effect'' in linear band pure silicon spin transport device with the presence of a perpendicular magnetic field. Spin diffusion-drift equation is used to provide an analytical transit time distribution of electrons. Final signal received at detector side is plotted as a function of perpendicular magnetic field intensity. Use this tool to understand the effects of oblique magnetization, injector/detector magnetization flipping and tilting on spin precession.
