thin films/ double resonant Raman scatteringExperimental results are presented on Raman scattering in graphite films produced by DC plasmaenhanced chemical vapor deposition from a methane-hydrogen gas mixture. Scanning electron and probe microscopy data show that, depending on substrate material and ...

2.04 and 2.11 eV. The spectra are fit to a sum of Lorentzians (grain and green curves). The second-order bands studied here are denoted p1, p2, p3and p4. (c,d) Resonant Raman maps of 1L and bulk MoS2acquired using more than twenty different laser lines, showing the enhancement...
Accordingly, it was proven that the use of an isotropic elastic shell model can lead to relevant errors in CNT vibration analysis, in particular to natural frequencies very different from those obtained by means of resonant Raman experimental spectroscopy or molecular dynamics numerical simulations, ...

Graphene was prepared by mechanical exfoliation using Kish graphite, Grade 200 (Graphene Supermarket, New York, USA). Silicon wafers were cleaned in a base piranha solution for 20 minutes at 85 °C, rinsed thoroughly with milliQ water, followed by ethanol rinsing, and dried with dry N2....
We present an analysis of deep-UV Raman measurements of graphite, graphene, and carbon nanotubes. For excitation energies above the strong optical absorption peak at the M point in the Brillouin zone (≈4.7 eV), we partially suppress double-resonant scattering processes and observe the two-...
Resonant Raman scattering of second-order Raman modes from an individual graphite whisker synthesized by a high-temperature heat-treatment method at a special pressure was discussed here. The dependence of phonon frequencies on the incoming laser light and the frequency difference between Stokes and ...
