Transport studies on CVD-grown graphene

In this thesis, we report transport studies performed on CVD-grown graphene. We perform resistivity and hall measurements on a large-area sample at 4' K. We measure the carrier mobility of the sample and find it to be on the order of 1000 cm2/Vs, whereas monolayer graphene regularly exhibits much higher mobilities. We also examine what we find to be weak signatures of Shubnikov-de Haas oscillations in magnetic field sweeps. Finally, we study magneto-resistance effects at low fields, and find that the sample exhibits weak-localization effects.
