Surface plasmons are collective oscillations of electrons in metals or semiconductors that enable confinement and control of electromagnetic energy at subwavelength scales. Rapid progress in plasmonics has largely relied on advances in device nano-fabrication, whereas less attention has been paid to the tunable properties of plasmonic media. One such medium—graphene—is amenable to convenient tuning of its electronic and optical properties by varying the applied voltage. Here, using infrared… 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
