Propagating edge and interfacial states in corrugated graphene: Robustness and configurability
The research investigates how periodic corrugations on graphene create a strain superlattice that generates a pseudomagnetic field and a scalar potential. This interplay leads to robust, propagating edge states within energy gaps, which are stable against disorder. The findings enable electrically switching these edge channels on and off using external potentials, paving the way for reconfigurable electronic devices.
