Here, the resistance of a WSe${}_{2}$ monolayer is measured under a strong, pulsed magnetic field. Non-$\frac{1}{B}$-periodic Shubnikov--de Haas oscillations are observed and attributed to a large spin-valley splitting of the valence band. The authors develop a model to simulate the magnetoresistancein the regime of partially resolved Zeeman splitting of the Landau levels. The ratio between the Zeeman and cyclotron energies, obtained from the fit of the oscillations, translates into a density…

Interactions and Magnetotransport through Spin-Valley Coupled Landau Levels in Monolayer MoS_{2}.
The strong spin-orbit coupling and the broken inversion symmetry in monolayer transition metal dichalcogenides results in spin-valley coupled band structures. Such a band structure leads to novel
Density-Dependent Quantum Hall States and Zeeman Splitting in Monolayer and Bilayer WSe_{2}.
Measurements in tilted magnetic fields reveal an insensitivity of the QHS to the in-plane magnetic field, evincing that the hole spin is locked perpendicular to the WSe_{2} plane, implying that the Zeeman-to-cyclotron energy ratio remains constant as a function of perpendicular magnetic field at a fixed carrier density, but changes as afunction of density due to strong electron-electron interaction.
Spin- and valley-dependent magneto-optical properties of MoS 2
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
Landau levels and Shubnikov-de Haas oscillations in monolayer transition metal dichalcogenide semiconductors
We study the Landau level (LL) spectrum using a multi-band theory in monolayer transition metal dichalcogenide semiconductors. We find that in a wide magnetic field range the LL can be characterized
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.
Orbital, spin and valley contributions to Zeeman splitting of excitonic resonances in MoSe 2 , WSe 2 and WS 2 Monolayers
We present a comprehensive optical study of the excitonic Zeeman effects in transition metal dichalcogenide monolayers, which are discussed comparatively for selected materials: MoSe$_2$, WSe$_2$ and
Determining Interaction Enhanced Valley Susceptibility in Spin-Valley-Locked MoS2.
The results provide evidence for many-body interaction effects in the conduction band of MoS2 and establish a fertile ground for exploring strongly correlated phenomena of massive Dirac electrons.
Ambipolar Landau levels and strong band-selective carrier interactions in monolayer WSe2
The Zeeman splitting in the VB is several times higher than the cyclotron energy, far exceeding the predictions of a single-particle model and, moreover, tunes significantly with doping, suggesting that ML WSe2 can serve as a host for new correlated-electron phenomena.
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
Exciton diamagnetic shifts and valley Zeeman effects in monolayer WS2 and MoS2 to 65 Tesla
Low-temperature polarized reflection spectroscopy of atomically thin WS2 and MoS2 in high magnetic fields to 65 T is reported, thereby quantifying the valley Zeeman effect in monolayer transition-metal disulphides.
