MoS2 Orientation (image) Brown University Caption Understanding the orientations of light emitters in layered nanomaterials and other thin films could lead to better optical devices. A new spectroscopy method allows researchers to distinguish these orientations. The angular distribution of light emission from monolayer MoS2, left, closely matches the theoretical calculations for in-plane oriented emitters, right, indicating that light emission from the graphene-like material MoS2 originates from in-plane oriented emitters.
