What Techniques Are Used to Measure Thermal Properties at the Nanoscale?
Measuring thermal properties at the nanoscale is challenging due to the small dimensions and the need for high precision. Some of the common techniques include:
Time-Domain Thermoreflectance (TDTR): A laser-based technique used to measure thermal conductivity and thermal boundary conductance. Scanning Thermal Microscopy (SThM): A variant of atomic force microscopy that measures temperature distribution and thermal conductivity at the nanoscale. 3-Omega Method: An electrical method used to measure thermal conductivity of thin films and nanowires.
