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.


Analytic spin precession simulator has been developed by Appelbaum Lab at University of Delaware, Newark, DE.
