| contents | Response enhancement of sprayed ZnO thin film-based NO2 sensor by indium-doping R. Ferro J. A. Rodríguez P. Bertrand M. Henry C. Poleunis Física, Astronomía y Matemáticas ZnO Gas sensor spray pyrolysis The development of a sprayed ZnO thin film–based NO2 sensor is reported. The effect of In–doping on the sensor performance is studied. With the addition of 3 wt % of indium nitrate to the spraying solution, a good sensor response to 5 ppm of NO2 at 275°C and an important decrease in the device electrical resistance is obtained. The dependence of the electrical resistance on temperature in several gas atmospheres is also considered. A possible sensitization mechanism is discussed. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57028295007 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
