Abstract

We are using of Zn2TiO4 thin film for H2 sensing. Zn2TiO4 thin film is formed on Si/SiO2 substrate
by a spin coating process and Al is used as electrodes. This device has excellent hydrogen (H2) gas sensing
properties. The phase and crystal structure of the thin film was studied using X-ray diffraction. The sensor
responds linearly at room temperatureto H2 gas concentrations ranging from 50 to 250 ppm and shows a good
sensitivity toward low ppm of H2. The response time of the sensor is about 76 s at 250-ppm H2. We could fit
the sensor response to the Langmuir adsorption model
