In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

The fascinating point of 2D and layered materials is that they can be assembled into van der
Waals (vdW) heterostructures, in which atomic layers are integrated by vdW force. There are …

The transport properties of relativisticlike fermions have been extensively studied in solid-
state systems with isotropic energy dispersions. Recently, several two-dimensional and …

We present a quantum switch based on analogous Dirac fermion optics (DFO), in which the
angle dependence of Klein tunneling is explicitly utilized to build tunable collimators and …

The sharp Dirac cone of electronic dispersion confers to graphene a remarkable sensitivity
to strain. It is usually encoded in scalar and pseudovector potentials, induced by the …

Hexagonal boron nitride (h-BN) crystals grown under ultrahigh pressures and ultrahigh
temperatures exhibit a high crystallinity and are used throughout the world as ideal …

Hexagonal boron nitride (h-BN) synthesized under high pressure and high temperature
(HPHT) has been used worldwide in two-dimensional (2D) materials research as an …

We articulate the challenges and opportunities of unconventional devices using the photon
like flow of electrons in graphene, such as Graphene Klein Tunnel (GKT) transistors. The …

Creation of sharp lateral p–n junctions in graphene devices, with transition widths w well
below the Fermi wavelength λF of graphene's charge carriers, is vital to study and exploit …

Graphene has excellent carrier mobility, making it highly suitable for high-speed electronics.
However, controlling the carrier flow still poses significant challenges due to the lack of an …
