Abstract
A gas sensor is disclosed, which includes two separate metal electrodes on a surface of a substrate and a semiconductor thin film deposited on the surface of the substrate and connecting the two metal electrodes. The semiconductor thin film contains zinc oxide or a mixed oxide of zinc and indium, and the zinc oxide or the mixed oxide of zinc and indium are in the form of nanowires which constitute a gas-sensing surface of the semiconductor thin film. The nanowires have a diameter of 50-900 nm. The present invention also discloses a method for detecting the presence of a NOx gas.
