Materials serve as the basis of societal development and the material of choice of a given
era is often a defining point. Everything we see and use in our daily life is made from …

The aim of this book is to introduce the basic elements of the scattering matrix approach to
transport phenomena in dynamical quantum systems of non-interacting electrons. This …

Since the advent of graphene, the two-dimension allotrope of carbon, there has been a
growing interest in calculation of quantum mechanical properties of this crystal and its …

Monolayer MoS2 is a typical valleytronic material with valley-spin locked valence bands. We
numerically investigate the valley-spin polarized current in monolayer MoS2 via adiabatic …

MXenes represent a new family of two-dimensional materials that have attracted
considerable attention in recent years. Because of the remarkably different structures of …

We investigate quantum charge pumping 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 studied the generation of valley dependent current by adiabatic quantum pumping in
monolayer graphene in the presence of electric potential barriers, ferromagnetic field and …

Quantum spin Hall effect was first predicted in graphene. However, the weak spin orbit
interaction in graphene meant that the search for quantum spin Hall effect in graphene never …

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 pumping …

Many recent calculations have been performed to study a Co atom adsorbed on graphene,
with significantly varying results on the nature of the bonding. We use the auxiliary-field …
