Highly Efficient Midinfrared On-Chip Electrical Generation of Graphene Plasmons by Inelastic Electron Tunneling Excitation
Kelvin J. A. Ooi, Hong Son Chu, Chang Yu Hsieh +2
Inelastic electron tunneling provides a low-energy pathway for the excitation of surface plasmons and light emission. We theoretically investigate tunnel junctions based on metals…

Efficiencies of Aloof-Scattered Electron Beam Excitation of Metal and Graphene Plasmons
Kelvin J. A. Ooi, Wee Shing Koh, Hong Son Chu +2
We assessed the efficiencies of surface plasmon excitation by an aloof-scattered electron beam on metals and graphene. Graphene is shown to exhibit high energy transfer efficiencie…
