This is an update of a previous review (Naumis et al 2017 Rep. Prog. Phys. 80 096501).
Experimental and theoretical advances for straining graphene and other metallic, insulating …

The presence of two sublattices in hexagonal graphene brings two energetically degenerate
extremes in the conduction and valence bands, which are identified by the valley quantum …

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) …

Mechanical deformations in α-T 3 lattices induce local pseudomagnetic fields of opposite
directionality for different valleys. When this strain is equipped with a dynamical drive, it …

We study the electronic transport through uniformly bent carbon nanotubes. For this
purpose, we describe the nanotube with the tight-binding model and calculate the local …

Nonuniform strain in graphene can induce a pseudomagnetic field (PMF) preserving time-
reversal symmetry, generating pseudo-Landau levels under zero real magnetic field (MF) …

Using the tight-binding model, we investigate the valley current of the “low-bi-up” and “low-bi-
low” graphene junction, where “low” and “up” are respectively the lower and upper …

The valley degree of freedom endows graphene with many novel physical properties. In this
paper, we propose a new method to construct valley-related quantum Hall states using side …

The tunnel current (TC) and valley current (VC) are crucial in realizing high-speed and
energy-saving in next-generation devices. This paper presents the TC and VC link in the …

We theoretically study valley-filtering in pristine graphene irradiated by bicircular counter-
rotating laser drive. The dynamical symmetry of the graphene and laser drive disrupts …
