摘要
A generalized tight-binding model is utilized to study Landau-level spectra of monolayer molybdenum disulfide. The intrinsic spin-orbit coupling effectively gives rise to multiple splitting of Landau levels. With a close inspection of wave-function characteristics, these levels can be classified into specific groups in terms of their orbital, spin, and valley signatures. In the calculation of magnetoabsorption spectra, the physical origin of the optical selection rules is clearly resolved. In particular, crossings of absorption lines are available and serve as a unique feature of the spin-orbit coupling. Our numerical results clearly demonstrate the magnetic control of spin and valley charge carriers and provide a basis for future experiments.
