This article provides a pedagogical review on Klein tunneling in graphene, ie the peculiar
tunneling properties of two-dimensional massless Dirac electrons. We consider two simple …

We review the energy spectrum and transport properties of several types of one-dimensional
superlattices (SLs) on single-layer and bilayer graphene. In single-layer graphene, for …

The elementary excitations of monolayer graphene, which behave as massless Dirac
particles, make it a fascinating venue in which to study relativistic quantum phenomena. One …

The time evolution of a wave packet in strained graphene is studied within the tight-binding
model and continuum model. The effect of an external magnetic field, as well as a strain …

We present a systematic study of the energy spectra of graphene quantum rings having
different geometries and edge types in the presence of a perpendicular magnetic field …

The current-voltage characteristics of a new range of devices built around Weyl semimetals
has been predicted using the Landauer formalism. The potential step and barrier have been …

Within an effective Dirac theory the low-energy dispersions of monolayer graphene in the
presence of Rashba spin-orbit coupling and spin-degenerate bilayer graphene are …

One of the key features of graphene is the chirality of the electrons originating from the lattice
symmetry. Conservation of the chirality leads to Klein and anti-Klein tunneling in graphene …

We show that the strong coupling of pseudospin orientation and charge carrier motion in
bilayer graphene has a drastic effect on transport properties of ballistic pnp junctions …

The α-T 3 lattice model interpolates a honeycomb (graphene-like) lattice and a T 3 (also
known as dice) lattice via the parameter α. These lattices are made up of three atoms per …
