BihurCrystal and the research group ESISNA (Structure of Nanoscopic Systems Group, of the Instituto de Ciencia de Materiales in Madrid) have begun a collaboration within the frame of the Retos-Colaboración 2015 call. This call is part of the Spanish National Programme for Research Aimed at the Challenges of Society that is financed by the European Regional Development Fund.
The joint project, called TESELA (tessera or tile in Spanish), will explore new bottom-up approaches for the obtention of high-quality graphene films directly on non-conductive substrates.
The most wide-spread method to produce graphene is by the decomposition of hydrocarbons on metal substrates, which act as catalyzers in this process. Graphene obtained in this way must then be transferred from the metal surface to a non-conductive substrate if it is to be used for technological application. This second step unavoidably degrades the graphene layer. The aim of TESELA is to eliminate this second step, and to obtain graphene layers directly on the non-conductive substrate using novel precursor molecules and evaporation techniques.
