WebJan 7, 2008 · Abstract. We have studied temperature dependences of electron transport in graphene and its bilayer and found extremely low electron-phonon scattering rates that set the fundamental limit on possible charge carrier mobilities at room temperature. Our measurements show that mobilities higher than 200 000 cm2/V s are achievable, if … WebJun 6, 2008 · Further measurements yield graphene's opacity of 2.3 ± 0.1% and negligible reflectance (<0.1%), whereas optical spectroscopy shows that the opacity is practically independent of wavelength, λ . The opacity is found to increase with membranes' thickness so that each graphene layer adds another 2.3% (Fig. 1B inset).
