Exciton Diamagnetic Shifts and Valley Zeeman Effects in Monolayer WS${}_2$ and MoS${}_2$ to 65 Tesla

Andreas V. Stier, Kathleen M. McCreary, Berend T. Jonker +2

We report circularly-polarized optical reflection spectroscopy of monolayer WS${}_2$ and MoS${}_2$ at low temperatures (4~K) and in high magnetic fields to 65~T. Both the A and the B e…
