Abstract:
Graphene being a unique two dimensional material has remained a material of great
attention ever since it’s isolated and characterized back in 2004. Despite an excellent
carrier mobility and thermal conductivity, the zero band gap of graphene needs to be
opened to make is useful in real life applications. For this sake self-assembled monolayer
provide a very wide range of molecular modification options. In particular the well-known
gold and thiol system provides has resilient functionalization options. The idea to combine
the strong covalently bonded gold and thiols system combined with the non-covalent
interaction with graphene, in order to retain the characteristic properties of graphene.
Graphene stacked over the nitro-functionalized thiols-Au (111) present p-type doping
effect being induced in the system. Leading to a promising electronic device application in
the field of graphene field effect transistor.
