Abstract
We measured the surface temperature of diamond films which had different morphologies from the intensity ratio of anti-Stokes to Stokes Raman lines for each laser power. Raman spectra show that the film having {111} morphology (after 21 h deposition) has the best diamond quality in this work. However, the measured surface temperature of well-faceted {100} morphology was found to be lowest among those of any other morphologies in this work, where heating was performed by the probing laser beam itself. Furthermore, the temperature rise with increasing laser power was found to be lowest in the film with well-faceted {100} morphology. From these results, it can be suggested that the film with well-faceted {100} morphology has the highest thermal conductivity.
