ZnO nanobelt based conductometric H<inf>2</inf>and NO<inf>2</inf>gas sensors

Conductometric H2and NO2gas sensors based on single-crystalline ZnO nanobelt sensitive layers have been developed. These layers were deposited using a rf magnetron sputterer. TEM and SEM characterization methods were employed to study the morphology of the nanobelts. These sensors were exposed to H2...
