  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.
