Elastic deformations of graphene can significantly change the flow paths and valley
polarization of the electric currents. We investigate these phenomena in graphene …

The field of valleytronics considers the creation and manipulation of “valley states”, charge
excitations characterized by a particular value of the crystal momentum in the Brillouin zone …

Using a simple setup to bend a flexible substrate, we demonstrate deterministic and
reproducible in situ strain tuning of graphene electronic devices. Central to this method is …

Klein tunneling refers to the absence of normal backscattering of electrons even under the
case of high potential barriers. At the barrier interface, the perfect matching of electron and …

There is a wide range of science and applications accessible via the strain engineering of
quantum transport in 2D materials. We propose a realistic experimental platform for uniaxial …

Tunneling transport across electrical potential barriers in Weyl semimetals with tilted energy
dispersion is investigated. We report that the electrons around different valleys experience …

The extreme mechanical resilience of graphene and the peculiar coupling it hosts between
lattice and electronic degrees of freedom have spawned a strong impetus toward strain …

We study the symmetry, magnetization, temperature and electrostatic gating effect on the
selective spin-valley polarized transport through the zigzag silicene nanoribbon (ZSiNR) …

In this work we investigate the effects of a Fermi velocity modulation in a valley filter in
graphene created by a combination of a magnetic and electric barrier. With the effective …

Valleytronics using two-dimensional materials opens unprecedented opportunities for
information processing using a valley polarizer as a basic building block. Various …
