Abstract
Micro-Raman spectra of thin films of various carbonaceous compounds are presented. The relative Raman scattering cross sections of films of graphite and diamond are revised (a factor of two is found instead of 50 as in literature). Second order and third order Raman spectra of graphite and diamond like films are presented and discussed in terms of resonance Raman effect. Study of carbonaceous thin films under electric field is in progress.
