What is Frequency Domain Thermoreflectance (FDTR)?
Frequency Domain Thermoreflectance (FDTR) is an advanced technique used to measure the thermal properties of materials at the nanoscale. FDTR relies on modulating the temperature of a sample using a laser and then detecting the resulting changes in reflectance. These changes are analyzed in the frequency domain, providing insights into thermal conductivity, thermal diffusivity, and other crucial thermal properties.
