Abstract
Free-standing Ca0.4Sr0.6Bi4Ti4O15 oriented ferroelectric thin films were deposited on water soluble NaCl (100) substrates using a sol-gel method at annealing temperatures ranging from 650 οC to 725 οC. When annealed at 700 οC, the Ca0.4Sr0.6Bi4Ti4O15 thin film with spherical shaped grains had the smallest strain: 0.2557%. The average size of the spherical shaped grains and surface roughness were close to 100 nm and 1.75 nm respectively.

Keywords: Ferroelectric thin film, Soluble substrate, Sol-gel.
