ABSTRACT

The paper reports on theoretical estimation of quantum electron tunneling rate from graphene sheet into some 3D media through a rectangular potential barrier. Tunneling from a lateral sheet surface and from its edge has been considered. We use perturbation theory and Bardeen transfer Hamiltonian approach to cope with the problem. The results show that tunneling current density from a free edge of a graphene may exceed greatly that from its lateral surface. That can explain observed higher emission current from carbon nanotubes with open edge compared to closed edge nanotubes.
