Resistance noise higher-order spectrums in nanoparticle gas sensors Conference Paper uri icon


  • The resistance fluctuations of sensors can give improved selectivity and sensibility and the analysis is limited to power spectrum density only. Non-Gaussian low frequency noise components can be observed in nanoparticle gas sensors especially if some of the characteristics length scales is in the submicron range. These components can be characterized by higher-order spectra (HOS). In this paper, bispectra and trispectra are used. The modulus and phase characteristics of the higher-order spectra of the observed resistance fluctuations are analyzed separately. The explored sensors consist of WO 3 films, with Pd nanoparticles uniformly distributed in the oxide structure.
