Abstract

The effect of nanosize grains to enhance dielectric tunability in chemically prepared (Pb1-x Sr (x) )TiO3 (PST) (x=0.1 to 0.5) thin films has been observed. The grain size is evaluated from X-ray diffraction patterns and atomic force microscopy. The average grain size lies in the range of 80-23 nm with varying Sr content. The nanosize grains in the PST films control the dielectric behavior up to the higher frequency region and exhibit large tunability with low loss factor at room temperature. The current-voltage characteristics show a large tunability as electron transport takes place within a highly resistive Fermi gap.
