摘要：

We report the fabrication and characterization of nanoscale ferroelectric structures consisting of disk-shaped nanomesas averaging 8.7+/-0.4 nm in height and 95+/-22 nm in diameter, and nanowells 9.8+/-3.3 nm in depth and 128+/-37 nm in diameter, formed from Langmuir-Blodgett films of vinylidene fluoride copolymers after annealing in the paraelectric phase. The nanomesas retain the ferroelectric properties of the bulk material and so may be suitable for use in high-density nonvolatile random-access memories, acoustic transducer arrays, or infrared imaging arrays. The nanomesa and nanowell patterns may provide useful templates for nanoscale molding or contact-printing. (C) 2004 American Institute of Physics.
