Sn0,(5 at.% Al) thin films have been grown by sputtering with the RGTO technique. The Urn response to NO2 and CO has been examined from d.c. to 4 MHz by means of impedance spectroscopy. Frequence intervals are found where the sensitivity to NO2 is increased with respect to the d.c. value. This prope
