WebThe strong light-matter interaction and the valley selective optical selection rules make monolayer (ML) MoS2 an exciting 2D material for fundamental physics and optoelectronics applications. But, so far, optical transition linewidths even at low temperature are typically as large as a few tens of meV and contain homogeneous and inhomogeneous contributions. WebAn alternative route to valley polarization is to lift the valley degeneracy by breaking time-reversal symmetry. Valley splitting in MX 2 has been assessed in a few recent experiments17-20, which showed that only small valley splitting, 0.1-0.2 meV/tesla, can be generated by an external magnetic field. Recent studies showed that
