Webbcapacitors [13]. In this way, systematic studies of misoriented graphene layers are quite interesting, and Raman spectroscopy plays an important role on its characterization, con-sidering that several previous works in the literature show that the Moiré patterns can activate new Raman peaks in the spectra. The Raman mechanism involves both the ... WebbBismuth films with thicknesses between 6 and ∼30 nm were grown on Si (111) substrate by molecular beam epitaxy (MBE). Two main phases of bismuth — α-Bi and β-Bi — were identified from high-resolution X-ray diffraction (XRD) measurements. The crystal structure dependencies on the layer thicknesses of these films were analyzed. β-Bi layers …

Raman spectra of misoriented bilayer graphene – arXiv Vanity

Webb( a) Raman spectra obtained in four different regions of a graphene sample that contains regions with single layer and bilayer regions. The spectrum on the top was recorded inside the Cu enclosure, and the other three were obtained in different regions outside of the Cu enclosure, with bilayer graphene (BLG) domains. Webb3 nov. 2006 · Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers.
