title: Free-standing ferroelectric nanotubes processed via soft-template infiltration.
abstract: A new nano-manufacturing method for the creation of high aspect-ratio ferroelectric (PbZr0.52Ti0.48O3) nanostructures by use of polymeric templates is presented. The ferroelectric response is characterized by band-excitation PFM, supporting the high quality of the nanostructures. Piezoelectric size effects for ferroelectric materials are reported for the first time in nanotube configuration (critical thickness ∼15 nm) and compared to thin films' response.
