Paper Abstract

The infrared absorption in microwave plasma-deposited, polycrystalline diamond films has been measured for the C-H stretch-mode and the diamond two-phonon mode, giving absorption coefficients of approximately 26 and 7.5 cm-1 respectively for a 20 micrometers thin film, assuming that the whole thickness of the film is responsible. The C-H absorption band envelope has been deconvoluted into its various components, allowing some estimation of the relative importance of CH, CH2, and CH3 grouping in the films. A significant absorption at approximately 3 micrometers due to N-H has been measured in films exposed to atomic nitrogen.
