There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Graphene-based Materials

Abstract:
Graphene-based materials hold promise due to their exceptional electronic and thermal
transport, mechanical properties, high specific surface area, and that they can act as an atom
thick layer, barrier, or membrane. Our early top-down micromechanical exfoliation
approaches [1,2] conceived of in 1998 yielded multilayer graphene. Two main research areas
of our group are: (i) CVD growth of large area graphene on metal substrates and studies of
such material, and (ii) the generation, study, and use of colloids consisting of graphene-based
platelets dispersed in liquids. An update of our work on CVD growth of graphene on metal
substrates ‘graphene’ colloidal suspensions will be given. A history of experimental work on
graphene (from discovery in 1969 to now) is provided at:
