Abstract
Yttrium titanate (Y2Ti2O7) thin films, having pyrochlore-type structure, were synthesized in single phase by sol-gel synthesis technique. Single-phase formation was confirmed by X-ray diffraction (XRD) study. Surface morphology of thin films was studied by using FESEM and average grain size was found to be in nanometer range. Retention of stoichiometry in thin films was confirmed by EDX analysis. Optical property of Y2Ti2O7 thin films was studied with the help of UV-Vis spectrometer and the energy band gap was found to be ∼3.5 eV. Dielectric properties of thin films are also studied and discussed in details.
