We have designed and batch-fabricated thin-film thermocouple cantilever probes for scanning thermal microscopy ͑SThM͒. Here, we report the use of these probes for imaging the phonon temperature distribution of electrically heated carbon-nanotube ͑CN͒ circuits. The SThM images reveal possible heat dissipation mechanisms in CN circuits. The experiments also demonstrate that heat flow through the tip-sample nanoscale junction under ambient conditions is dominated by conduction through a liquid
