The ability to manipulate optical fields and the energy flow of light is central to modern information and communication technologies, as well as quantum information processing schemes. However, because photons do not possess charge, a way of controlling them efficiently by electrical means has so far proved elusive. A promising way to achieve electric control of light could be through plasmon polaritons—coupled excitations of photons and charge carriers—in graphene. In this two-dimensional… Expand

Plasmon transport in graphene investigated by time-resolved electrical measurements
TLDR
It is demonstrated that the plasmon velocity can be changed over two orders of magnitude by applying a magnetic field B and screening the plAsmon electric field with a gate metal; at high B, edge magnetoplasmons are formed and their velocity depends on B, n and the gate screening effect. Expand

TLDR
It is shown that surface plasmon resonances in graphene can be enhanced locally at the atomic scale, using electron energy-loss spectrum imaging in an aberration-corrected scanning transmission electron microscope to find that a single point defect can act as an atomic antenna in the petahertz (10(15) Hz) frequency range, leading to surface plasmons resonances at the subnanometre scale.
