Photothermal radiometry measurement of thermophysical property change of an ion-irradiated sample

Using photothermal radiometry (PTR) an ion-irradiated ZrC sample's thermal properties are measured by fitting frequency-scan data to a theoretical model for the surface temperature. The technique is shown to measure thermal properties without physical contact of a very small sample.
