We have assembled tin dioxide nanobelts with low-power microheaters for detecting dimethyl methylphosphonate (DMMP), a nerve agent simulant. The electrical conductance of a heated nanobelt increased for 5% upon exposure ...

We have measured the thermal conductivities of a 53-nm-thick and a 64-nm-thick tin dioxide (SnO₂) nanobelt using a microfabricated device in the temperature range of 80–350 K. The thermal conductivities of the nanobelts ...
