摘要: Abstract The members of the p-type semiconducting SrTi 1− x Fe O 3− δ family perovskites have been studied as novel materials for hydrocarbon sensor applications. Screen-printed thick film devices are contrasted to thin films prepared by pulsed laser deposition (PLD). In order enhance specificity towards hydrocarbons, influence iron content, , thickness and operating temperature in range from 300 500 °C has investigated. addition, use a catalytically active cover layer made platinum-doped zeolite successfully reduce species with cross-interference. An initial model explaining underlying sensing mechanism is proposed.
