New Platform Generates Hybrid Light-Matter Excitations in Highly Charged Graphene

Caption

Massive work function-mediated charge transfer in graphene/?-RuCl3 heterostructures provides the necessary conditions for generating plasmon polaritons without electrostatic or chemical doping. The image depicts a characteristic infrared near-field image of such a heterostructure, revealing a host of plasmonic oscillations derived from substantial mutual doping of interfacial graphene/?-RuCl3 layers.
