10 Questions
What are some advantages of graphene oxide membranes in terms of filtration?
Perfect barrier, effective separation of organic solvent from water, exceptional water removal from gas mixture
How could graphene supercapacitors impact the weight of cars or planes?
Reduce weight
What is the potential application of graphene in storing wind and solar power?
Grid applications and storing wind or solar power
Who were the two researchers at The University of Manchester who isolated single-layer graphene in 2004?
Andre Geim and Konstantin Novoselov
What was the initial reaction to Andre and Kostya's paper on one-atom-thick graphene sheets when they first published it?
It was rejected twice as it was thought so unlikely that one-atom-thick sheets could be stable.
What significant event occurred after Andre and Kostya's paper on graphene was finally published in the journal Science in 2004?
It sparked a global explosion in graphene research.
What are the difficulties associated with the epitaxial growth of graphene on SiC?
Difficulty in controlling the thickness, transferring the film, and achieving uniform deposition of carbon.
Describe the main concept behind the process of epitaxial growth of graphene on SiC.
Heating the SiC wafer causes Si to evaporate, leaving behind graphene layers on SiC.
How does UHV (Ultra High Vacuum) technique influence the growth of graphene on SiC?
It hinders the uniform growth of Multi-Layer Graphene (MLG) and favors bilayer graphene.
What happens during the epitaxial growth process that leads to the formation of graphene layers on SiC?
Si atoms evaporate due to thermionic emission, leaving behind carbon atoms on the substrate.
