IntroductionWhat Is Graphene And Why Do We Care?• Graphene = one-atom-thick sheet of (sp2-bonded) carbon atoms• Like 1 layer in graphite• 2D material = new class of materials• Lots of Superlatives:• Thinnest material (1 atomic layer)• Largest surface area (2700sqm/g)• Strongest material ‘ever measured’ (theoretical limit)• Stiffest known material (stiffer than diamond)• Most stretchable material (20% elastically)• Record thermal conductivity (outperforming diamond)• Highest current density at RT (10^6 x Cu)• Completely impermeable (even to He)• Highest intrinsic mobility (100x Si)• Conducts electricity in the limit of no electrons• Lightest charge carriers (zero rest mass)• Longest mean free path at RT6/27/13 Bruker Nano Surfaces19
