The transport properties of a twisted bilayer graphene barrier are investigated for various
twist angles. Remarkably, for small twist angles around the magic angle θm∼ 1.05°, the …

We investigate the low-energy electronic transport across grain boundaries in graphene
ribbons and infinite flakes employing two distinct techniques. Using the recursive Green's …

Graphene bilayer systems are known to exhibit a band gap when the layer symmetry is
broken by applying a perpendicular electric field. The resulting band structure resembles …

The transmission across a graphene bilayer region is calculated for two different types of
connections to monolayer leads. A transfer-matrix algorithm based on a tight-binding model …

In this work we study, as a function of the height V and width L b of the potential barriers, the
transport of Dirac quasi-particles through quantum dots in graphene ribbons. We observed …

In bilayer graphene, the top layer and the bottom layer can be regarded as a kind
of'pseudospin'. By applying a voltage bias between the two layers, the pseudospin is …
