a Schematic of the modified meter-bar thermal measurement setup (not to scale). b Example thermal infrared image of the meter bars, electrodes and spacer. Heat flows from the bottom (hot side) to the top (colder side). c Extracted temperature profile from (b). The blue asterisks are the experimental temperature measurements and the magenta solid curve is the non-linear fitting. The temperature data points near the interface were not used in the fitting due to low thermal emissivity of the electrodes. To reduce noise, we averaged ~1000 video frames for each thermal measurement. Vertical error bars are one standard deviation and horizontal error bars are ~0.6 mm (one pixel)
