• Rajasekaran et al. [77] found no difference between single- and few-layer graphene (both measured at 284.0 eV). On the other hand, Emtsev et al. [64] and Hibino et al. [73] measured the C 1s energy of mono- to few-layer graphene epitaxial on silicon carbide as a function of the number of layers, and found

• some of these factors, a very recent measurement using synchrotron-based scanning X-ray photoelectron microscopy assigned a value of 400.92 eV to substitutional N in suspended ion-irradiated few-layer graphene [67]. In any case, the range of values cited for the substitution seems so large that

Covalently functionalized few-layer graphene with the bipyridine ruthenium complex (2,2′-bipyridyl)-4-pyridyl-ruthenium(II)chloride, Ru(bpy)2(py)Cl, results in the formation of

• few layer graphene (FLG) is highly attractive from an application point of view, due to its extraordinary electronic properties. In order to study its properties, we demonstrate and discuss three different routes to in situ create and identify (twisted) FLG. Single layer graphene (SLG) sheets

• point of view due to its angle-dependent electronic properties [4][5][6][7][8][9][10]. Twisted few layer graphene (FLG) exhibits electronic properties ranging from Dirac cones found for single layer graphene (SLG) for rotation angles over 15° where the layers are effectively decoupled, to a Fermi

• velocity renormalization for smaller rotation angles [8][9][10][11]. For very small rotation angles, θ ≤ 2°, the electronic properties are found to be coupled to the resulting moiré spots for twisted BLG [10]. In order to study these properties experimentally, (few layer) graphene can be produced in
