We investigate quantum charge pum** through the surface states of a topological
insulator (TI), ie, Bi 2 Te 3. We consider a device with two oscillating potentials for the …

We study quantum-charge and spin-transport properties and the effects of in-plane strain on
the charge and spin currents in a phosphorene monolayer using an adiabatic pum** …

The interplay between various internal degrees of freedom of electrons is of fundamental
importance for designing high performance electronic devices. A particular instance of this …

Finite-layer nanoribbon materials have long been considered as potential candidates for
nanodevices with novel quantum effects. Here we constructed a series of ferromagnetic …

All-electrostatic generation and control of both spin and valley polarizations provides a
highly promising route towards much smaller and energy-efficient nanoscale devices …

We propose a graphene nanoribbon pum** device and study its quantum charge and
spin pum** properties for both adiabatic and non-adiabatic regimes by using the Keldysh …

Previous studies of electronic transport in molybdenum disulfide (MoS2) are restricted to the
first order approximation of the Hamiltonian. In this paper, to obtain more exact results, we …

Strong spin–orbit coupling and lack of inversion symmetry in monolayer transition metal
dechalcogenides has made these materials as a promising candidate for both spintronic …

The recently predicted penta-RuS 4 monolayer with high stability, large nontrivial band gap
and robustness against oxidation is promising for applications in nanoelectronics. The band …

Although the existence of four valley degrees of freedom in the (0 0 1) surface of IV–VI
semiconductor topological crystalline insulators (TCIs) provides the opportunity to multiply …
