Resolving the spin splitting in the conduction band of monolayer MoS2

Abstract

In monolayer transition-metal dichalcogenides, lack of inversion symmetry results in spin-split valence and conduction bands, but the small conduction band splitting is hard to probe experimentally. Here, the authors extract a sub-band spacing energy of 0.8 meV in the conduction band of monolayer MoS2 via quantum transport measurements.
