Abstract

The thermal transport behavior of CVD diamond films with different thicknesses (1 - 100 micrometers ) has been investigated by high frequency modulated photothermal reflectance technique. By analyzing the frequency dependent phase behavior of the laser-induced thermal waves, we have obtained the thermal conductivity of the samples as well as the thermal resistance at the film-substrate interfaces. With the tabled values of the density and the specific heat, we then calculate the thermal diffusivities and compare them with previously reported data on similar samples. The results demonstrate the technique a powerful tool for investigating the demanding diamond coatings.
