We present the science and technology roadmap for graphene, related two-dimensional
crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts …

The nonlinear optical and optoelectronic properties of graphene with the emphasis on the
processes of harmonic generation, frequency mixing, photon drag and photogalvanic effects …

We compare the three most commonly used scanning probe techniques to obtain a reliable
value of the work function in graphene domains of different thickness. The surface potential …

We present a new fabrication method for epitaxial graphene on SiC which enables the
growth of ultra-smooth defect-and bilayer-free graphene sheets with an unprecedented …

The quantum Hall effect provides a universal standard for electrical resistance that is
theoretically based on only the Planck constant h and the electron charge e. Currently, this …

The characteristics of tunnel junctions formed between n-and p-doped graphene are
investigated theoretically. The single-particle tunnel current that flows between the two …

The quantum Hall effect can be substantially affected by interfacial coupling between the
host two-dimensional electron gases and the substrate, and has been predicted to give rise …

We explore the robust quantization of the Hall resistance in epitaxial graphene grown on Si-
terminated SiC. Uniquely to this system, the dominance of quantum over classical …

Replacing GaAs by graphene to realize more practical quantum Hall resistance standards
(QHRS), accurate to within 10− 9 in relative value, but operating at lower magnetic fields …

Carrier density and temperature-dependent transport properties of monolayer graphene
grown on SiC (0001) were systematically studied. With increasing temperature, resistivity at …
