Popis: (Pb 0.92 La 0.08 )(Zr 0.65 Ti 0.35 )O 3 (PLZT) thin films with TiO 2 buffer layers were deposited on Pt/Ti/SiO 2 /Si substrates by R.F. magnetron sputtering method in order to improve the ferroelectric characteristics of the films; and the ferroelectric properties and crystallinities of the PLZT thin films were investigated in terms of the effects of the post-annealing temperatures of TiO 2 buffer layers between a Pt bottom electrode and a PLZT thin film. The ferroelectric properties of the PLZT thin films improved as the post-annealing temperatures of TiO 2 layers increased, reaching their maximum at 600 °C and decreasing thereafter.
