Cadmium stannate (Cd2SnO4) thin films were
prepared by the RF magnetron sputtering technique on glass
substrates with substrate temperatures of room temperature
(RT), 100°C, 200°C and 300°C. Photoacoustic analyses
were made to obtain the thermal diffusivity and the
optical bandgap values of the Cd2SnO4 thin films. The
change in thermal diffusivity of the films with the substrate
temperature was analyzed. The optical bandgap values
obtained from the photoacoustic spectroscopy were
compared with the values obtained from the optical transmittance
spectra. X-ray photoelectron spectroscopic (XPS)
studies confirm the formation of stoichiometric films. Surface
morphological studies by atomic force microscopy
(AFM) revealed the crystalline nature of the films deposited
at 100°C
