Giant valley splitting in monolayer WS(2) by magnetic proximity effect

Lifting the valley degeneracy of monolayer transition metal dichalcogenides (TMDs) would allow versatile control of the valley degree of freedom. We report a giant valley exciton splitting of 16 meV/T for monolayer WS(2), using the proximity effect from an EuS substrate, which is enhanced by nearly...
