Observation of regions of negative differential conductivity and current generation during tunneling through zero-dimensional defect levels of the $h$-BN barrier in graphene/$h$-BN/graphene heterostructures
Abstract:
Tunneling and magnetic tunneling are investigated in graphene/$h$-BN/graphene van der Waals heterosystems. Two new types of systems are found, in which negative differential conductivity regions are implemented due to resonant tunneling through defect levels in the $h$-BN barrier, and current caused by their presence is generated.
