We investigate the behavior of low-energy electrons in two-dimensional molybdenum disulfide when submitted to an external magnetic field. Highly degenerate Landau levels form in the material, between which light-induced excitations are possible. The dependence of excitations on light polarization and energy is explicitly determined, and it is shown that it is possible to induce valley and spin polarization, i.e. to excite electrons of selected valley and spin. Whereas the effective low-energy…

Magnetic control of valley and spin degrees of freedom via magnetotransport in n-type monolayer MoS2.
It is predicted that the valley- and spin-resolved Hall conductance obeys the same rule as that for conventional fermions, but the first Hall plateau and the longitudinal charge conductance in low energies are fully valley/spin-polarized, which may produce a pure valley/ spin current.
Valley- and spin-polarized Landau levels in monolayer WSe2.
The observation of fully valley- and spin-polarized LLs in high-quality WSe2 monolayers achieved by exploiting a van der Waals heterostructure device platform is reported.

Effect of valley, spin, and band nesting on the electronic properties of gated quantum dots in a single layer of transition metal dichalcogenides
We present here results of atomistic theory of electrons confined by metallic gates in a single layer of transition metal dichalcogenides. The electronic states are described by the tight-binding
Optical Investigation of Monolayer and Bulk Tungsten Diselenide (WSe₂) in High Magnetic Fields.
Optical spectroscopy in high magnetic fields B ≤ 65 T is used to reveal the very different nature of carriers in monolayer and bulk transition metal dichalcogenides. In monolayer WSe2, the exciton

It is shown that through modifying atomic d-orbitals conduction and valence band states by an applied electric field, one can determine and control the impact of a magnetic field on the optical response of these materials.
