摘要：

A new nano-manufacturing method for the creation of high aspect-ratio ferroelectric (PbZr 0.52Ti 0.48O 3) 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 μ15 nm) and compared to thin films' response.
