Exciton g-factors in monolayer and bilayer WSe2 from experiment and theory

Abstract

Excitons in various spin and valley configurations control the optical properties of ultrathin transition metal dichalcogenides. Here, the authors develop theoretical and experimental methods to determine the exciton g-factors for all possible spin-valley configurations of excitons in monolayer and bilayer WSe2, including valley-indirect excitons.
