ABSTRACT
The measurements of the thermal diffusivities of several freestanding CVD-diamond films performed in the frame of a round robin test are presented in detail. The measurements were done at room temperature using a modified version of the dynamic Angstrom method, developed for studies of freestanding films. It was found that thermal diffusivities and conductivities could be correlated with the densities and IR-transmission spectra of the different specimens. The discrepancies with the average thermal conductivity results of the round robin test could not be explained from the uncertainty of our method.
