Graphene-based materials are of interest because of their electronic and thermal transport, mechanical properties, high specific surface area, and that they can act as an atom thick layer, barrier, or membrane, among other reasons. Our micromechanical exfoliation approaches [1,2] conceived of in 1998 yielded multilayer graphene and one paper described in detail how monolayer graphene could be obtained [1]. Three main research areas of our group are: (i) Growth of large area graphene on metal substrates, characterization and physical properties, and studies of devices having such CVD-grown graphene as a central component; (ii) Generation, study, and use of chemically modified graphene ‘platelets’ (typically derived from graphite oxide) including as dispersed in liquids forming colloids, and powders derived from such colloids or separately generated by microwave or thermal treatment of graphite oxide; (iii) Generation and study of new types of carbon derived from graphene-based precursors, such as activated microwave expanded graphite oxide (‘aMEGO’)[3].
Here, I will focus on growth of graphene and h-BN from research projects underway in my group and also briefly describe what I think are some important new directions in carbon and first row element research, for the next 10-20 years, that will introduce new issues involving interfaces for these new material classes that have not yet been made experimentally [4].
Current or prior support of our work by the W. M. Keck Foundation, NSF, DARPA ‘iMINT’, DARPA ‘CERA’, ONR, SWAN NRI, ARO, AEC, DOE, and the SRC, is appreciated.
