What Does PMTR Stand For?

PMTR stands for Photomodulated Thermoreflectance

PMTR, or Photomodulated Thermoreflectance, is a non-destructive optical technique used to characterize materials by analyzing their thermal and optical properties. This method involves the modulation of light to induce periodic heating in a sample, which in turn leads to changes in reflectance. By measuring these reflectance changes, researchers can gain insights into various material parameters, including thermal conductivity, film thickness, and electronic properties, making PMTR a valuable tool in fields such as materials science, nanotechnology, and semiconductor research.
