The citrate complexing sol–gel process to fabricate lead-free (K,[Formula: see text]Na)NbO3 ferroelectric thin films was studied. Soluble niobium source of niobium–citric acid (Nb–CA) solution was utilized as a raw material to synthesize (K,[Formula: see text]Na)NbO3 thin films, by pyrolyzing at 450–550[Formula: see text]C and annealing at 650[Formula: see text]C. The film pyrolyzed at 450[Formula: see text]C shows poor crystallization with porous morphology, whereas the film pyrolyzed at 550[Formula: see text]C appear to be well-crystallized and denser, and the ferroelectricity was also proved by the [Formula: see text]–[Formula: see text] hysteresis loop measurement.

Metallic Conduction

LSMO films with various thicknesses were prepared on single crystal Si (111) substrates by sol-gel process. The films were dense and had a uniform microstructure. The films showed metallic conduction characteristics at low temperature and insulator characteristics at high temperature. The metal-insulator transition temperatures (Tmi) of the films were remarkably lower than that of the bulk ceramics. The effect is related to the distortion of crystal lattice resulted from the residual stress in the films.
