Anisotropic attosecond charge carrier dynamics and layer decoupling in quasi-2D layered SnS2

Abstract

Owing to their layered nature, transition metal dichalcogenides possess an anisotropic electronic structure whose impact on carrier dynamics is not fully known. Here, the authors use X-ray spectroscopy to unveil the electronic coupling and attosecond dynamics in SnS2, a prototypical van der Waals layered crystal.
