Zinc oxide nanobelts by RF sputtering for ethanol sensor

Zinc oxide nanobelts by RF sputtering for ethanol sensor

Zinc oxide nanobelts were RF sputtered onto a copper tube. Their nanostructure has been confirmed by FE-SEM and Raman spectroscopy. The copper tube coated with these ZnO nanobelts was then employed as an ethanol gas sensor. To characterize the sensor, experiments with ethanol at concentration levels...
