Abstract

The Debye radius (r_D) is a useful parameter that describes the performance of a semiconductor material to be used as sensors and transducers. Tin oxide-Ferrous oxide (SnO₂-Fe₂O₃) composite films were fabricated on glass substrates with varying temperatures of 300, 325, and 350°C. Scanning electron microscopy showed an onset of crystallite formation for films deposited at temperatures higher than 300°C. X-ray diffractometry showed an increase in crystallite size with increasing deposition temperatures. Fitting the voltage response with sigmoidal functions as well as its linearization led to the calculation of r_D and the pyroelectric coefficient p_V.
