Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferro- and piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measuring the local piezoelectric hysteresis. A sharp switching at the coercive voltage of about 2 V was shown from the hysterisis loop. The corresponding effective remnant piezoelectric coefficient is about 90 pm/V. We also expect that free-standing ferroelectric nanotubes obtained by partial etching of the silicon template will be used as building blocks of miniaturized devices and can have a significant impact in the field of nano-electromechanical systems.}, year = {2003}, journal = {Integrated Ferroelectrics}, volume = {59}, pages = {1513-1520}, issn = {10584587}, doi = {10.1080/10584580390260009}, note = {cited By 41}, language = {eng}, }
