Nine‐nanometer‐thick ferro‐ and piezoelectric nanocrown patterns consisting of crystalline BaTiO 3 have been prepared by pulsed laser deposition using latex sphere monolayer masks. The unusual crown‐like shape of the nanopattern is achieved by selecting the appropriate high ambient pressure during deposition. The ferro‐ and piezoelectric properties were investigated by AFM in piezoresponse mode.
