Researchers Confirm Strong Magneto-Optical Resonance in Graphene

The interaction between graphene and light suggests that graphene could be used to control infrared (IR) and terahertz (THz) waves. Researchers from the University of Geneva (UNIGE) and the University of Manchester have demonstrated an efficient way to control IR and THz waves using graphene, in a study that confirms a 2006 theory predicting that graphene could be used in a magnetic field to absorb THz and IR light on demand and control the direction of the circular polarization. “There exist a class of the so-called Dirac materials, where the electrons behave as if they do not have a mass, similar to the light particles, the photons,” researcher Alexey Kuzmenko said. One such material is graphene, which is composed of a...
