Klein Tunneling through Double Barrier in ABC‐Trilayer Graphene

Résumé

Abstract Klein tunneling and conductance for Dirac fermions in ABC‐stacked trilayer graphene through symmetric and asymmetric double potential barrier are investigated. This was done by using the continuum model of two and six‐bands. The numerical results show that the transport is sensitive to the height, the width, and the distance between the two barriers. It is found that the Klein paradox at normal incidence () and resonant features at in the transmission result from resonant electron states in the wells or hole states in the barriers. It is shown that such features strongly influence the ballistic conductance of the structures.
