For over a decade, graphene materials have been the focus of extensive theoretical and experimental research because of graphene’s unique physical and chemical properties, which make it a potential candidate for many technological applications. Despite the success of graphene in many domains, the material's zero band-gap property and its relative chemical inertness have limitations for applications which require a fraction of an eV bandgap and/or a stable doping mechanism. These problems may be solved by graphene nanomeshes (GNMs), which are graphene-based structures made by forming a lattice of pores in graphene. In my talk, I will demonstrate the feasibility of doping GNMs using a novel chemically-motivated approach, which we have shown to be stable, with a high degree of control over concentration for both n and p type doping. I will also discuss some of the potential applications for GNMs in nanoelectronics, catalysis and molecular sensing.
All faculty, researchers and graduate students are invited to attend.
