In this paper platinum (Pt) doped tungsten trioxide (WO3) layers have been investigated. The structures were prepared in the standard thick film technology. A scanning electron microscope (SEM) was used for the microstructure analysis of the gas sensitive layers. The work function was examined by using a scanning Kelvin probe (SKP). The Kelvin probe is a non-contact and non-destructive method to provide...
Celem badań było określenie wpływu domieszek metali szlachetnych (Pt, Au) na strukturę i parametry warstwy gazoczułej opartej na WO₃ rezystancyjnych czujników gazów. Analiza widm uzyskanych z wykorzystaniem XPS potwierdziła skład warstw. Dodatek metali szlachetnych zarówno w ilości 3,2%, jak i 6,5% nie wpłynął na położenie i kształt pików odpowiadającym orbitalom charakterystycznym dla W, Pt i Au...
