What Techniques are Used to Measure Heat at the Nanoscale?
Measuring heat at the nanoscale requires advanced techniques:
1. Scanning Thermal Microscopy (SThM): This technique uses a sensitive thermal probe to measure temperature distributions with nanometer resolution. 2. Raman Spectroscopy: It can be used to measure local temperature changes by analyzing the shift in the vibrational modes of molecules. 3. Thermoreflectance: This method measures changes in the reflectivity of a material as a function of temperature. 4. Micro-Raman Thermometry: This technique involves using Raman scattering to determine the temperature of nanomaterials.
