... of the Semiconductor Gas Sensors (SGS´2004) Seminar, 19 22.9.2004, Ustron, Poland. TULE Research Programme Progress Report 2005 1New materials and structures for semiconductor gas sensors ... semiconductor gas sensors, and in particular gas sensors using SnO2 as a sensing material, are based on polycrystalline thin or thick films. Sensing mechanisms of these types of sensors have been ... systems for gas sensor materials based, e.g., on the Kelvin probe techniques, which allow in situ studies of the gas reactions at the sensor surfaces. The new epitaxial and layered semiconductor...
