Abstract

Different compositionally graded Pb_XSr_1-xTiO₃ (x=0.2, 0.3, 0.4, 0.5 and 0.6) (PST) thin films were deposited on LaNiO₃(LNO)-buffered stainless steel (SS) substrates. Both LNO and PST thin films were prepared by the sol-gel method. X-ray diffraction and scanning electron microscopy analysis were used to investigate the crystallinity and surface morphology of PST thin films. It showed that the crack-free PST thin films presented pure perovskite phase. The temperature and frequency stability of tunability has been improved. The change rate of tunability could be less than 5% in a wide range of temperature.
