INVESTIGATION ON THE PREPARATION AND MECHANISM OF FERROELECTRIC(Pb, La)TiO_(?) THIN FILMS BY SOL-GEL PROCESSING

摘要

Wc have analyslsed the raw materlals of PZT and its sol and gel by the infrared absorption spectrum. Using sol-gel processing, PZT epitexial thin films with perovskite structure on SrTiO?, MgO and sapphire single crystal substrates, and PLT ceramic thin films with pervoskite structure on Si single crystal
