This is similar to Klein tunneling, which, in a monolayer, is instead responsible for perfecttransmission at normal incidence. Stacking defaults turn each parabolic band crossing of a bilayerinto pairs of Dirac cones. Here we show that…

Stacking defect‐induced electronic cloaking of confined states and Fano resonance in zero‐energy shifted bilayer graphene

We show that a stacking defect or a shift has a striking effect on transport properties of bilayer graphene. The tunneling through a ballistic n–neutral–n junction of shifted bilayer graphene may

In-plane magnetoelectric response in bilayer graphene

A graphene bilayer shows an unusual magnetoelectric response whose magnitude is controlled by the valley-isospin density, making it possible to link magnetoelectric behavior to valleytronics.

Destruction of anti-Klein tunneling induced by resonant states in bilayer graphene

The anti-Klein tunneling at normal incidence is a typical property of bilayer graphene. We study the resonant tunneling through multiple electrostatic barriers in bilayer graphene, and find that a

Confined states in graphene quantum blisters

It is demonstrated that confinement in GQB persists even in the presence of a variation in the inter-layer coupling, and the energy levels in G QB exhibit electron-hole symmetry that is sensitive to the electrostatic bias.

Optical Properties of Graphene in Magnetic and Electric fields

Optical properties of graphene are explored by using the generalized tight-binding model. The main features of spectral structures, the form, frequency, number and intensity, are greatly enriched by

Herein, the electronic structure of Dirac fermions scattered by double barrier potential in graphene under strain effect is studied. It is shown that traction and compression strains can be used to

The layered graphene systems exhibit the rich and unique excitation spectra arising from the electron-electron Coulomb interactions. The generalized tight-binding model is developed to cover the
