The Graphene Group in the J. Heyrovsky Institute of Physical Chemistry of the CAS is exploring and exploiting some exceptional properties of graphene. Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms densely packed in a hexagonal honeycomb crystal lattice. The Graphene Group currently focuses on the mechanical and electrochemical alteration of its electronic structure and observes the response to these changes by various methods, mainly with Raman spectroscopy. Although graphene had been studied theoretically for decades, its actual existence was not proven until 2004, when Kostya Novoselov and Andrei Geim from Manchester University isolated a monolayer for the first time. In 2010 they were awarded the Nobel Prize. Nano Letters deals with bilayer graphene and the possibility of a band-gap opening through inhomogeneous strain fields.
