We will use theoretical modeling to assist experiments in order to explore the different characters of graphene and boron doped graphene coatings in a nanoplasmonic sensor based on a novel graphene – copper heterostructure [1]. The sensing function is achieved via the theoretically predicted “socket-plug” strategy [2] and it is due to the significant changes in the interface dielectric properties between the graphene layer and its support when switching from a) a bare metal surface to a graphene coating; when b) replacing a conventional graphene coating by a boron doped graphene one, and when c) molecular adsorbates bind to the latter. This application (based on AoA Nano funding) concerns a joint experimental and theoretical effort between Chemistry (Prof. Itai Panas and Dr. Valentina Cantatore) and Physics (Prof. Christoph Langhammer) to provide a proof of concept, which will pave the way for a robust technological platform for sensors based on boron doped graphene – copper plasmonic nanoparticle heterostructures.
