  Prof. Yunjiang Rao’s group published a paper “Broadband gate-tunable THz plasmons in graphene heterostructures” on Nature Photonics. Collaborators of this work include University of California, Los Angeles (UCLA), Cambridge Graphene Centre, Institute of Microelectronics, etc.
  In this paper, Yao demonstrate a counter-pumped all-optical difference frequency process to coherently generate and control THz plasmons in atomic layer graphene with an octave tunability and high efficiency. This work was highly appraised by reviewers.
