GAS SENSOR HAVING AG-DOPED ZNO NANOWIRE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A gas sensor having a silver-doped zinc oxide nano wire and a method for manufacturing the same are provided to differentiate gas sensing sensitivity because a change of electrical properties is induced by doping silver, thereby selectively sensing various harmful gases. CONSTITUTION: A gas sensor comprises a substrate(11), an insulation film(12), azinc oxide nano wire(13), and a plurality of electrodes(14). The insulation film is formed on the substrate. The zinc oxide nano wire is arranged on the insulation film and silver is doped. The electrodes are arranged on the insulation film by being spaced from each other and electrically connected to the nano wire.
