A graphene/n-type silicon heterojunction has been demonstrated to exhibit strong rectifying behavior and high photoresponsivity. By introducing a thin interfacial oxide layer, the dark current of graphene/n-Si heterojunction has been reduced by two orders of magnitude at zero bias.
Graphene is the only form of carbon (or solid material) in which every atom is available for chemical reaction from two sides (due to the 2D structure). Atoms at the edges of a graphene sheet have special chemical reactivity. Graphene has the highest ratio of edge atoms of any allotrope. Defects within a sheet increase its chemical reactivity ...
The electronic properties of graphene are significantly influenced by the supporting substrate. [59] [60] The Si(100)/H surface does not perturb graphene's electronic properties, whereas the interaction between it and the clean Si(100) surface changes its electronic states significantly. This effect results from the covalent bonding between C ...

The Graphene Flagship is a European Union scientific research initiative. [1] With a budget of €1 billion, it is one of the large scale initiatives organized by the Future and Emerging Technologies program, along with the Human Brain Project and the Quantum Technologies Flagship.
The Centre for Advanced 2D Materials (CA2DM), at the National University of Singapore (NUS), is the first centre in Asia dedicated to graphene research. [1] The centre was established under the scientific advice of two Nobel Laureates in physics – Prof Andre Geim and Prof Konstantin Novoselov - who won the 2010 Nobel Prize in Physics for their discovery of graphene.
