| Abstract: | A thermal conductivity measurement system for photothermal deflection thin films was successfullydeveloped according to the priciple of Photothermal Deflection Spactroscopy(PTDS).A large number ofsamples of thin films were measured and the results agreed well with the reference data in the literatures.Itsrepeatation accuracy was better than 5%. It provides a powerful measure for the study of thermalproperties of materials,in particular, for photothermal deflection thin films,and it has been making animportant contribution to the improvement of thermal property in diamond films. |
