Abstract

Hydrogen sensors have been fabricated from single SnO ₂ nanobelts synthesized via catalyst-free thermal evaporation. Ohmic contacts were defined on individual SnO ₂ nanobelts by photolithography and pulsed laser deposition of RuO ₂. The sensitivity and response time of the sensors, without any catalyst on the surface, to 2% hydrogen at temperatures between 25 and 80°C were measured. Sensitivity greater than 50%, response time <220 s, and power consumption <10 nW at room temperature were demonstrated.
