Structural parameters significantly influence the resonant tunneling behavior.

Resonant features strongly impact the ballistic conductance of graphene structures.

Abstract

Resonant electronic transmission through graphene-based double barriers (wells) is studied as a function of the incident wave vector, the widths and heights (depths) of the barriers (wells), and the separation between them. Resonant features in the transmission result from resonant electron states in the wells or hole states in the barriers and strongly influence the ballistic conductance of the structures.
