Abstract

Self-assembled nanoskyscrapers of ferroelectric Bi4 Ti3 O12 were fabricated by a bottom-up process: flux-mediated epitaxy using an admixture flux. By combinatorial technique, we have discovered a novel flux, V Ox, to assist the unique crystal growth for the in-plane alignment of the long c axis of Bi4 Ti3 O12 on a SrTi O3 (001) substrate. We report on the self-assembly of an isolated epitaxial (110)-oriented Bi4 Ti3 O12 nanoplate and the direct measurement of the piezoelectric properties by a scanning probe microscope technique. Piezoelectric lattice displacement showed a typical butterfly curve, indicating good ferroelectric property.
