Abstract | |||||||||||
| The sensing behaviour of three kinds of Bi-based superconductor film, differint in microstructure, has been studied. The films comprise Bi2Sr2CaCu2O8+x (BSCCO) with "open neck" contacts between grains, Bi2Sr2CuO6+x (BSCO) prepared by electronic beam evaporation and Bi2Sr2CaCu2O8+x with "Schottky-barrier-limited" conductance. The sensitivity and selectivity to NO and NO2 gases against CO and CO2 have been investigated. The flow rate dependence of the NOx sensitivity has bee measured | |||||||||||
