“…The use of multi-wavelength laser sources can also help improve deconvolution reliability as the fitted results can be checked against the expected excitation energy dispersive behaviour [23,31,32,[40][41][42][43].…”

“…1(d) are presented. The frequency fits well into the linear dispersion relation of peak shift and laser excitation energy found in earlier experiments [11]. In addition, we find that the peak is narrower and down-shifted at the edge of the single layer while it is somewhat broader and displays a shoulder at the crossover from the double to the single layer.…”

Abstract. Graphite is a well-studied material with known electronic and optical properties. Graphene, on the other hand, which is just one layer of carbon atoms arranged in a hexagonal lattice, has been studied theoretically for quite some time but has only recently become accessible for experiments. Here we demonstrate how single-and multi-layer graphene can be unambiguously identified using Raman scattering. Furthermore, we use a scanning Raman set-up to image few-layer graphene flakes of various heights. In transport experiments we measure weak localization and conductance fluctuations in a graphene flake of about 7 monolayer thickness. We obtain a phase-coherence length of about 2 µm at a temperature of 2 K. Furthermore we investigate the conductivity through single-layer graphene flakes and the tuning of electron and hole densities via a back gate.

“…This ratio has previously been shown to be laser wavelength dependent on a linear relation in the VIS region. 22 Raman investigations of graphite in the carbonaceous meteorites Allende and Axtell with laser excitations at 785 and 1064 nm showed experimentally that this linear dependence is extended in the NIR region.…”
