EN

Photoacoustic effect and photothermal radiometry were applied to characterise the thermal properties of diamond crystallites which were coated by a Cu film, a Cr film and a Cr-Cu film. The Cu-coated diamond exhibits a considerable thermal barrier at the Cu-diamond interface which had disappeared for the crystallites with a thin bond Cr layer between diamond and Cu. The comparison of the responses of both measurement techniques reveals the non-negligible influence of the optical absorption in the visible and IR on the deduced thermal parameters.
