Abstract

Raman spectroscopy measures molecular vibrations by analyzing the frequency components of scattered laser light. It will provide information about the composition, crystallinity, stress, and spatial distribution of the various types of carbon found in diamond films. The general composition of diamond films can be investigated by monitoring bands in the Raman spectrum at 1332 cm^-1 for crystalline diamond, 1580 cm^-1 for graphite, and a broad band around 1350 cm^-1 for amorphous material. The bandwidth of the 1332 cm^-1 band is indicative of the crystal quality. Stress variations in diamond result in wavenumber shifts of the 1332 cm^-1 band in the Raman spectrum. The internal stress in differently oriented diamond films has been investigated using Raman microscopy and was found to vary along the length of a crystallite. Using Raman mapping, it is possible to determine the spatial distribution of diamond and non-diamond carbon on the surface of a diamond film. The resulting gray scale images allow the regions of high diamond concentration to be identified.
