| Popis: | In this work we demonstrate the synthesis of millimetre-sized single-crystals of graphene, achievable in a commercially-available cold-wall CVD reactor, and several different approaches to transfer it from the growth substrate to a target substrate of choice. We confirm the high crystal quality of this material using various characterisation techniques, including optical and scanning electron microscopy as well as Raman spectroscopy. By performing field effect and quantum Hall effect measurements we demonstrate that the electronic properties of such single-crystals are comparable to those of ideal mechanically exfoliated flakes of graphene. Several applications of this high-quality material are also reviewed. Comment: 7 pages, 8 figures |
