Regular patterns of ferroelectric PbTiO3 nanostructures (see Figure) with lateral dimensions down to 30–60 nm have been grown onto platinized Si substrates by chemical solution deposition. The high registration of the grains is achieved by “top–down”-generated templates of TiO2 dots as seeds for their deposition. Ferroelectricity was verified by piezoresponse force microscopy.
