Abstract

The Pt-doped $SnO_2$ thin film for CO sensor applications obtained by RF sputtering from a target of the same compound in an Ar-$O_2$ atmosphere. Pt-SnO2-SiC Schottky diode detection of CO gas Cause the remarkable change in electrical resistivity of the semiconductor. the good gas sensitivity is shown when annealing condition is 600$^{\circ}C$, 1hr in RTP and detected temperature is 350$^{\circ}C$.
