Plasmons in graphene have unusual properties and offer promising prospects for plasmonic
applications covering a wide frequency range, ranging from terahertz up to the visible …

This article gives a brief overview of the linear and nonlinear optical response of graphene
and its applications. Graphene exhibits unique physical properties. The charge carriers in …

The generation of valley current is a fundamental goal in graphene valleytronics but no
practical ways of its realization are known yet. We propose a workable scheme for the …

We demonstrate theoretically how local strains in graphene can be tailored to generate a
valley-polarized current. By suitable engineering of local strain profiles, we find that …

We propose a simple, yet highly efficient and robust device for producing valley polarized
current in graphene. The device comprises of two distinct components; a region of uniform …

Despite much anticipation of valleytronics as a candidate to replace the aging
complementary metal-oxide-semiconductor (CMOS) based information processing, its …

We put forward a two-terminal valley filter based on a bulk graphene sheet under the
modulations of both a local perpendicular magnetic field and a substrate strain. When only …

We review the transmission properties of carriers interacting with potential barriers in
graphene. The tunneling of electrons and holes in quantum structures in graphene is found …

The controlled flow of spin and valley pseudospin is key to future electronics exploiting these
internal degrees of freedom of carriers. Here, we discover a universal possibility for …

Kelvin probe force microscopy (KPFM) has been employed to probe charge carriers in a
graphene/hexagonal boron nitride (hBN) heterostructure [Nano Lett. 21, 5013 (2021) …
