The Hersam Research Group specializes in the synthesis, purification, functionalization, and application of low-dimensional nanoelectronic materials including monodisperse carbon nanotubes, graphene, plasmonic nanoparticles, transition metal dichalcogenides, hexagonal boron nitride, black phosphorus, and borophene. Surface chemical functionalization allows further tunability over the properties of these low-dimensional nanoelectronic materials including self-assembled monolayers on epitaxial graphene, covalent functionalization of graphene epoxide, monolayer molybdenum disulfide, graphene nanoribbons on germanium, surface passivation of black phosphorus, and organic-borophene heterostructures. The integration of these diverse materials into mixed-dimensional van der Waals heterostructures enables significant advances in diverse applications including thin-film transistors, memristors, transparent conductors, photovoltaics, batteries, and biomedical imaging contrast agents. In addition to fundamental studies, the Hersam Research Group commercializes low-dimensional nanoelectronic materials through scalable nanomanufacturing methods such as continuous flow solution processing and a range of printing methods encompassing inkjet, aerosol jet, gravure, screen, and 3D printing.
