Abstract

The work presents the results of Raman studies of carbon nanofilms containing Pd nanostructural films. The samples were obtained in two step method: physical (PVD) and  physical/chemical deposition (PVD/CVD). Due to CVD modification of the PVD substrate films carbon nanofoam  is formed.  The analysis of Raman spectra confirms the presence of various carbon allotrope forms . For the PVD samples fullerite  and nanographite grains are observed. For the CVD samples the amorphous carbon and/or graphite-like structure are observed.

  C-Pd films containing Pd nanocrystals can be applied as active layers in proposed gas sensor applications
