Abstract
Molybdenum oxide thin films for gas sensing devices were deposited by rf reactive sputtering of a molybdenum target in Ar-O-2 atmosphere. Th en, a detailed structural, optical and electrical analysis was perform ed. The gas sensing features of deposited thin films were obtained by analysing the electrical response towards NO gas in the range 10 to 40 0 ppm. Electrical measurements showed that sputtered molybdenum oxide films are suitable for NO detection at operating temperatures of about 200 degrees C.
