Abstract

Thin nano- to microcrystalline diamond (N/MCD) films were deposited on silicon substrates using plasma enhanced microwave chemical vapor deposition. Selected layers were covered with a thin metal layer of Cr to enhance their optical absorption characteristics for photothermal and photoacoustic experiments. A heterodyne diffraction method was used to investigate the thermoelastic signatures of the N/MCD layers. While the dispersion of surface acoustic waves turned out to be difficult to determine due to high optical scattering from the diamond crystallites, it was found that a diamond film of ~ 2 μm thick is enhancing the thermal diffusion along the surface.
