Наблюдение областей отрицательной дифференциальной проводимости и генерации тока при туннелировании через нульмерные уровни дефектов барьера h-BN в гетероструктурах графен/h-BN/графен

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.
