Probing plasmons in graphene

ORAL

Abstract

Plasmon behaviour in graphene is important for the understanding of many body interaction of 2D Dirac fermions. It also provides physical background for potential graphene applications in optoelectronics and ultrahigh speed THz electronics. In this talk, we will describe our study of plasmon behaviour in graphene using far-infrared spectroscopy and compare our experimental results to theoretical predictions.
