Revealing in plane g factors in multilayer WSe2 via time-resolved Faraday experiments — •Simon Raiber, Dennis Falter, and Christian Schüller — Universtiät Regensburg
With the increasing investigation of two-dimensional heterostructures, the question arises how far the layer-intrinsic properties are imparted to multilayer van der Waals structures. While the effects of external magnetic fields on transition metal dicalcogenides monolayers have been studied intensively during the last years, the interaction of multiple layers remained largely disregarded.
We demonstrate a non-zero effective g factor for in plane magnetic fields in few-layer WSe2 making use of time-resolved Faraday rotation experiments. The found values commensurate to the established out of plane effective g factors. This indicates an isotropic effective in plane g factor for multilayer WSe2, which stands in contrast to monolayer samples. Up to now no standard theoretical approach can model an non-zero in plane g factor.
