  journal={Physical Review B},
The magnetically-induced valley-spin filtering in transition metal dichalogenides promises new paradigm in information processing. Herein, the mechanism of this effect is elucidated within the metal-induced gap states concept. The filtering is shown to be primarily governed by the valley-spin polarized tunnelling processes, which yield fundamental scaling trends for valley-spin selectivity with respect to the intrinsic physics of the filter materials. The results are found to facilitate insight…

Valley polarized current and resonant electronic transport in a nonuniform MoS2 zigzag nanoribbon

Using the tight-binding approach we study the electronic transport in a $\mathrm{MoS}_2$ zigzag ribbon with a spatially varying potential profile. Considering a ribbon with a smooth potential step in

Valley aspect of lateral tunneling transport

We theoretically study the valley aspect of lateral tunneling transport in valleytronic materials, using AB-stacked (Bernal-stacked) bilayer graphene as a material example. A lateral structure with

Progress in Contact, Doping and Mobility Engineering of MoS2: An Atomically Thin 2D Semiconductor

Atomically thin molybdenum disulfide (MoS2), a member of the transition metal dichalcogenide (TMDC) family, has emerged as the prototypical two-dimensional (2D) semiconductor with a multitude of

Valleytronics in 2D materials

The energy extrema of an electronic band are referred to as valleys. In 2D materials, two distinguishable valleys can be used to encode information and explore other valleytronic applications.

Quantum magnetotransport properties of a MoS 2 monolayer

We study transport properties of a MoS2 monolayer in the presence of a perpendicular magnetic field B. We derive and discuss its band structure and take into account spin and valley Zeeman effects.
