This paper reports on room temperature Raman scattering studies of ultrathin graphitic films supported on Si (111)/SiO₂ substrates. The films, containing from 1 to 20 graphene layers, exhibit unique Raman spectra that differ significantly from those of graphite. The 1st and 2nd order Raman spectra show distinct signatures of the number of layers in the film. The G-band, analog to the graphite G-band, exhibits a Lorentzian lineshape with a center frequency that shifts linearly with the reciprocal of the number of layers, ~1/n (for n=1, ωG=1588 cm⁻¹). Three weak bands at ~1350, 1450, and 1500 cm⁻¹, associated with disorder-induced 1st order scattering, are observed. The 1500 cm⁻¹ band shows an interesting n-dependence. Three 2nd order bands are also observed at ~2450, ~2700, and 3248 cm⁻¹, with the 2700 cm⁻¹ band exhibiting a dramatic change in shape with n. For n<5, the 2nd order band is more intense than the G-band. The study also discusses the electrical transport properties of ultra-thin graphite films and the importance of interlayer forces in supported n-graphene layer films. The Raman scattering results provide a method to identify the number of graphene layers in the films, which is crucial for understanding their electronic and phononic properties.This paper reports on room temperature Raman scattering studies of ultrathin graphitic films supported on Si (111)/SiO₂ substrates.
