What Techniques are Used to Study Thermal Radiation at the Nanoscale?
Several advanced techniques are employed to study nanoscale thermal radiation: 1. Scanning Thermal Microscopy (SThM): This technique provides high-resolution thermal imaging at the nanoscale. 2. Near-Field Scanning Optical Microscopy (NSOM): Used to study near-field radiative heat transfer phenomena. 3. Fourier Transform Infrared Spectroscopy (FTIR): Employed to analyze the spectral characteristics of thermal radiation from nanomaterials. 4. Photothermal Deflection Spectroscopy: Measures the change in refractive index due to thermal radiation absorption in materials.
