Revealing exciton masses and dielectric properties of monolayer semiconductors with high magnetic fields

The rational design of optoelectronic devices based on 2D materials relies on quantitative knowledge of their excitonic properties. Here the authors perform circularly-polarized absorption spectroscopy on monolayer $${{\rm{MoS}}}_{2},{{\rm{MoSe}}}_{2},{{\rm{MoTe}}}_{2}$$ MoS2,MoSe2,MoTe2 and $${{\rm...
