How Can We Measure Phonon Transport in Nanostructures?
Several experimental techniques are used to measure phonon transport in nanostructures, including:
Time-Domain Thermoreflectance (TDTR): A laser-based technique that measures thermal conductivity by analyzing the response of a material to a pulsed laser. Raman Spectroscopy: This technique can provide information about phonon modes and their interactions by analyzing the inelastic scattering of light. 3-Omega Method: A technique that measures the thermal properties of materials by applying an alternating current to a metal line deposited on the material's surface.
