Characteristics of diamond films

Since the fundamental difference between the various allotropes of carbon is the bonding state betwèen carbon atoms one of the most unambiguous methods of determining the bonding condition is the use of Raman spectroscopy. Figs. 2, 3 show typical attention. Defects in the film as well as the mix of structures represented by crystalline, microcrystalline and amorphous phases alter the Raman spectrum and introduce a variety of subsidiary peaks at various wavenumbers. The first order Raman spectrum of diamond consists of a single line at 1332 cm
