Abstract
RF magnetron sputtered Nasicon and sodium carbonate ionic conductive t hin films (2000 Angstrom) have been characterized using physical-chemi cal methods such as Auger electron spectroscopy (AES), X-ray photoelec tron spectroscopy (XPS), scanning electron microscopy (SEM) and electr ochemical impedance spectroscopy (EIS). It is found that the overall c hemical composition of sputtered and of laser deposited films is simil ar to that of the sputtering target. The Nasicon films show a sufficie ntly high ionic conductivity (0.36 S cm(-1) at 360 degrees C) for use in a prototype integrated CO2 sensor with the dimensions of 3 x 4 mm.
