CVD graphene for electrical quantum metrology

Graphene, a single atom thick material with carbon atoms arranged in a hexagonal lattice is widely being touted as the new wonder material for its interesting electrical and mechanical properties [1]. In particular, the observation of the Quantum Hall effect (QHE) in graphene has opened the way for a new quantum standard of resistance. Our research focuses on QHE and Raman characterization of chemical vapor deposited (CVD) graphene. In this paper we describe the CVD growth of graphene films, their transfer to substrates and their characterization using Raman spectroscopy and electrical transport measurements.
