A new electromagnetic mode in graphene
arXiv:cond-mat/0703406 · doi:10.1103/PhysRevLett.99.016803
Abstract
A new, weakly damped, {\em transverse} electromagnetic mode is predicted in graphene. The mode frequency $Ï$ lies in the window $1.667<\hbarÏ/μ<2$, where $μ$ is the chemical potential, and can be tuned from radiowaves to the infrared by changing the density of charge carriers through a gate voltage.
