General Properties of Graphene Electron transport High electron mobility at room temperature (200,000 cm2·V−1·s−1, achieved = predicted) limited by scattering by the acoustic phonons Resistivity = 10−6 Ω·cm (less than the resistivity of silver) Optical phonons of the substrate (ex. SiO2 ) limits the mobility to 40,000 cm2·V−1·s−1. Also dopant and ripples increase the resistivity Optical Electrons behave as massless two-dimensional particles => wavelength-independent absorption (=2.3%) for normal incident light below ~ 3 eV (very high opacity for an atomic monolayer) Mechanical Young modulus of 1TPa (steel 200GPa) and intrinsic strength of 130GPa (very close to theory) (carbon fiber 4GPa) Thermal Record high thermal conductivity and can sustain extremely high densities of electric current (million times higher than copper) 4/16/2014 V.
