The sensors are in the configuration LaFeO3/YSZ/Pt and will be used for the detection of NOx gases. The resistance variation of LaFeO3 layers under NO2 was also tested. The influence of the deposition temperature and of nature of the substrate on the morphology of the sensing electrodes (thin LaFeO3 layers) was investigated by Transmission Electron Microscopy (TEM) X Ray Diffraction (XRD) Scanning Electron Microscopy (SEM). Sensors were exposed to various concentration of NO2 in the temperature
range 500 - 800 °C and the sensing properties related to the morphology of the sensing electrodes.
