Metal-Insulator Transition from Graphene to Graphane
Graphane is obtained by perfectly hydrogenating graphene. There exists an intermediate material, partially hydrogenated graphene (which we call hydrographene), interpolating from pure graphene to pure graphane. Employing a graph theoretical approach to the site-percolation model, we present an intuitive and physical picture revealing a percolation transition from graphene to graphane. It is dem...
متن کاملHigh-pressure hydrogenation of graphene: towards graphane.
The conversion of graphene to graphane is of high importance from a technological and scientific point of view. We present here a scalable method for the hydrogenation of graphene based on thermal exfoliation of graphite oxide in a hydrogen atmosphere under high pressure (60-150 bar) and temperature (200-500 °C). This method does not require a plasma source and is able to produce gram quantitie...
متن کاملGraphene: Here comes graphane? : Article : Nature Chemistry
Another possible modification, which has been predicted theoretically, is the addition of hydrogen atoms to graphene — creating 'graphane' — altering the sp2 carbon atoms to sp3 and thus changing the structure and electronic properties. Now Andre Geim from the University of Manchester and co-workers from Russia and the Netherlands have hydrogenated mechanically exfoliated graphene by exposing i...
متن کاملToward high throughput interconvertible graphane-to-graphene growth and patterning.
We report a new route to prepare high quality, monolayer graphene by the dehydrogenation of graphane-like film grown by plasma-enhanced chemical vapor deposition. Large-area monolayer graphane-like film is first produced by remote-discharged radio frequency plasma beam deposition at 650 °C on Cu/Ti-coated SiO(2)-Si. The advantages of the plasma deposition include very short deposition time (<5 ...
