    • Abstract

       

      This work highlights some physical properties of Sb$_2$O$_3$ thin films obtained through heat treatment of Sb$_2$S$_3$ thin films under an atmospheric pressure at 400$^{\circ}$C. The obtained material is characterized by X-ray diffraction and impedance spectroscopy. X-ray diffraction analysis shows that Sb$_2$O$_3$ thin films were crystallized in cubic structure having a preferential growth along (222) plane. The grain size is found to be around 65 nm. The electrical conductivity was studied using impedance spectroscopy technique in the frequency range from 5 Hz to 13 MHz at temperatures lying in 638–698 K domain. Besides, the frequency and temperature dependence of the complex impedance, a.c. conductivity and complex electric modulus have been investigated.
