We report the first unambiguous ferroelectric properties of ultra-thin-walled Pb(Zr,Ti)O-3 (PZT) nanotube arrays, each with 5 nm thick walls and outer diameters of 50 nm. Ferroelectric switching behavior with well-saturated hysteresis loops is observed in these ferroelectric PZT nanotubes with P-r and E-c values of about 1.5 mu C cm(-2) and 86 kV cm(-1), respectively, for a maximum applied electric field of 400 kV cm(-1). These PZT nanotube arrays (10(12) nanotubes cm(-2)) might provide a competitive approach toward the development of three-dimensional capacitors for the terabyte ferroelectric random access memory.
