Giant intrinsic photoresponse in pristine graphene
Nature nanotechnology, Volume 14, Issue 2, 2018, Pages 145-150.
When the Fermi level is aligned with the Dirac point of graphene, reduced charge screening greatly enhances electron-electron scattering. In an optically excited system, the kinematics of electron-electron scattering in Dirac fermions is predicted to give rise to novel optoelectronic phenomena. In this paper, we report on the observation ...More
