HYDROGEN SENSITIVITY OF SnO_2-MnO FILM PREPARED BY ELECTROSTATIC SPRAY PYROLYSIS
ESP工艺制备SnO2—MnO薄膜的氢敏特性

SnO_2-MnO film were fabricated by electrostatic spray pyrolysis(ESP). The change in resistance of these film upon exposed to H2 gas in air have been measured. The results shown that the film has higher resistance in air and higher sensitivity to H2 gas. T
