Abstract

In this research, the gas sensing properties of cadmium metal oxide semiconductor fabricated using low frequency AC electrophoretic deposition toward pollutant gases such as NO2 and CO were investigated. For the electric field-assisted method, the parameters affecting the deposition pattern including frequency and the medium of deposition along with the dominant deposition mechanism in different frequency intervals in the range of 1 Hz to 10 kHz were studied using co-planar gold electrodes. SEM and Optical microscopy strongly show that the formation of CdO nanoparticles chains along with electrodes was the distinguished effect which was observed in the acetone suspension at frequency of 10 KHz. Gas sensing tests were performed on platinum-based comb-like electrodes towards different concentration of NO2 and CO gases using a normal dynamic gas sensing setup. The deposition of CdO nanoparticles was done at the frequency of 10 KHz, voltage of 30V and time duration of 5 min. The attained chain like structures of ceramic particles of CdO can be providing favorite sensing properties. The gas sensing results for different NO2 and CO gases throughout the 200-300 oC illustrated that the response increase as function of gas concentration and maximum response was achieved at 250 oC. Besides, the dynamic responses of CdO sensor for different NO2 and CO gas concentration confirmed the n-type behavior of CdO metal oxide Gas sensor as well as repeatability manner of present study.
