Abstract
Bi2Ti2O7 thin films were successfully prepared on n-type Si(100) substrate by using chemical solution decomposition (CSD) technique followed by rapid thermal annealing (RTA). The structural properties were studied by X-ray diffraction (XRD) and atomic force microscopy (AFM). The dielectric properties of the films were evaluated. The leakage current density of Bi2Ti2O7 thin films is of the order of 10-7A/cm2 when the applied voltage is between -18 and +18V. It is much lower than that of films treated by normal thermal processing. The dielectric constant varies from 159 to 150 within the frequency range of 10-100KHz, while the dissipation factor is lower than 0.02 in this range.
