Figure 3: Piezoelectric and ferroelectric properties of the transferred PZT on Si.

(a) Piezoforce microscopy of the transferred layer. The ferroelectric domains can be reversibly poled and the states are very stable. (b) The d33 coefficient of the transferred Pb(Zr0.2Ti0.8)O3 on Si. (c,d) P-E and C-E loop of a SrRuO3/ Pb(Zr0.2Ti0.8)O3/SrRuO3 transferred on highly doped Si substrate.
