Transcript of Graphene Presentation
Wonder Element:Graphenea presentation by:Nikhil Raina & Shivam SinhaCanadian International School
introductionOne atom thick of graphiteGraphene is the strongest, thinest material known to existIt is the basic structural allotrope.
existenceThe first patent records of graphene was filed in 2002 entitled, Nano-Scaled Graphite PlatesTwo years later, Andre Geim and Kotsya Novoselov extract graphene crystallites from bulk graphite.They both receive a noble prize in physics in 2010
chemical propertiesGraphene is chemically the most reactive form of carbonThe carbon atoms are strongly bonded within the plane in honeycomb array comprised of six-membered rings.Graphene burns at a very low temperature of 350 degrees Celsius
electronic propertiesIt is a zero-overlap semimetal (with both holes and electrons as charge carriers) with very high electrical conductivity.Electrons are able to flow through graphene more easily than through even copper.The electrons travel through the graphene sheet as if they carry no mass, as fast as just one hundredth that of the speed of light.High charge carrier mobility, for which values of 10,000 cm2/Vs, in some cases even 200,000 cm2/Vs were reported.
