SUMMARY
The discussion focuses on measuring the thermal conductivity of thin films, specifically comparing it to nanowires. The key formula for calculating thermal conductivity (k) is provided as $$k = \frac{Q}{A\Delta T}$$, where Q represents heat flow, A is the cross-sectional area, and ΔT is the temperature gradient. To accurately measure thermal conductivity in thin films, one must assess the temperature gradient using thermocouples or other temperature sensors, or by evaluating the power dissipated in the film.
