How is the Thermoreflectance Coefficient Measured?
The measurement of the thermoreflectance coefficient typically involves the following steps:
Illuminating the sample with a light source. Monitoring the reflected light intensity as the sample temperature is varied. Calculating the change in reflectivity with temperature to determine the thermoreflectance coefficient.
Advanced techniques, such as pump-probe methods, are often employed to achieve high temporal and spatial resolution in these measurements.
