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 … WebThe Nobel Prize in Physic s 2010 honours two scientists, who have made the decisive contributions to this development. They are . Andre K. Geim. and . Konstantin S. Novoselov, both at the University of Manchester , UK. They have succeeded in producing, isolating, identifying and characterizing graphene. 1,8. 2.
