Quantum Anomalous Hall Effect and Spin-filter Design Under the Control of Light and Exchange Field
We advance the theory that achieving quantum Hall effect in silicone can be possible.We investigate that a bulk band gap can be reopened by regulating optical and exchange field.Through tuning these external fields,perfectly nearly 100%spin-filter can be achieved with interesting spin separated edge state and be verified by calculating the spin polarizability.This finding provides a platform for designing high efficiency spin-filter.
