Abstract

The thermal conductivities of a 53-nm-thick and a 64-nm-thick tin dioxide (SnO ₂) nanobelt was measured using a microfabricated device in the temperature range of 80-350 K. The sample was kept in an evacuated continuous flow liquid-helium cryostat during the measurement. It was observed that the thermal conductivities of the nanobelts were strongly suppressed compared to the bulk values. It was shown that a dc current (I) was supplied to one Pt serpentine to raise the temperature of the membrane supporting the serpentine.
