Research ArticleOpen accessEvery word in the titleMathematical Modeling and Interpretation of PbPc Gas Sensor ArrayNidal F. Shilbayeh, Mahmoud Z. IskandaraniThe voltage/current characteristics and the effect of NO2 gas on the electrical conductivity of a PbPc gas sensor array is investigated. The gas sensor is manufactured using vacuum deposition of gold electrodes on sapphire substrate with the lead-phathalocyanine vacuum sublimed on the top of the gold electrodes. Two versions of the PbPc gas sensor array are investigated. The tested types … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling and Characterization of Thin Film, Narrow Gap Sensor Array Units (SAU)Mahmoud Z. IskandaraniDesign, modeling, testing and analysis multi-gap PbPc sensor array units for the purpose of gas detection are carried out. The tested devices showed reduction in conductance as a function of increasing gap width and reducing film thickness and an increase as a function of temperature up to 160°C. An observed morphological change in the sublimed film is realized at 190°C … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 6,856 accessesView PDFCite
