Abstract

Ferroelectric lean-titanate thin films were fabricated by sol-gel processing. Sol-gel derived $PbTiO_3$ thin films crystallized into the expected tetragonal perovskite structure when heated to $600^{\circ}C$ and above. The effects of annealing temperature on grain size made with SEM observation are reported. The films heated at $650^{\circ}C$ for 30min showed a square-type hysteresis loop with $P_r$ and $E_c$ of $11.5{\mu}C/cm^2$, 115kV/cm, respectively.
