Piezoresponse in Ferroelectric PZT Thin Films
Published online by Cambridge University Press: 26 February 2011
Abstract
Poled ferroelectric lead zirconate titanate (PZT) films comprising a (111) texture on (100)Si/SiO2/(111)Pt substrates were investigated by piezoresponse force microscopy (PFM). Depending on the film thickness, the crystallite orientation varies from purely (111) (related to the Pt bottom electrode orientation) to a more random texture. By PFM, 90° domains with a width of 50 nm were obtained in an individual grain Pb(Pb0.10Zr0.21Ti0.69)O3 − PPZT (10/21/69). It was shown that the virgin (unpoled) films possess large piezoelectric activity comparable to that after local poling (self-polarization effect). This corresponds to a clear predominance of the domains with a polarization oriented from the bottom electrode to the free surface of the film.
