Graphene quantum dots (GQDs) not only have potential applications on spin qubit, but also
serve as essential platforms to study the fundamental properties of Dirac fermions, such as …

The speed of silicon-based transistors has reached an impasse in the recent decade,
primarily due to scaling techniques and the short-channel effect. Conversely, graphene (a …

Electrostatic confinement of charge carriers in graphene is governed by Klein tunnelling, a
relativistic quantum process in which particle–hole transmutation leads to unusual …

We analyze bound modes of two-dimensional massless Dirac fermions confined within a
hyperbolic secant potential, which provides a good fit for potential profiles of existing top …

Scientists are always yearning for new and exciting ways to unlock graphene's true
potential. However, recent reports suggest this two-dimensional material may harbor some …

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 …

We show how it is possible to trap two-dimensional massless Dirac fermions in spatially
inhomogeneous magnetic fields, as long as the formed magnetic quantum dot (or ring) is of …

Creation of high-quality pn junctions in graphene monolayer is vital in studying many exotic
phenomena of massless Dirac fermions. However, even with the fast progress of graphene …

Searching for new states of matter and unusual quasi-particles in emerging materials and
especially low-dimensional systems is one of the major trends in contemporary condensed …

We use the Wick-rotated time-dependent supersymmetry to construct models of two-
dimensional Dirac fermions in the presence of an electrostatic grating. We show that there …
