Momentum alignment of photoexcited carriers in graphene: The route to optovalleytronics

Momentum alignment of photoexcited carriers in graphene: The route to optovalleytronics

A linearly polarized excitation is shown to create a strongly anisotropic distribution of photoex­cited carriers in graphene, where the momenta of photoexcited carriers are aligned preferentially normal to the polarization plane. This hitherto overlooked effect offers an experimental tool to gen­era...
