Abstract

We report the first unambiguous ferroelectric properties of ultra-thin-walled Pb(Zr,Ti)O₃ (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 μC cm^-2 and 86 kV cm^-1, respectively, for a maximum applied electric field of 400 kV cm^-1. These PZT nanotube arrays(10¹² nanotubes cm^-2) might provide a competitive approach toward the development of three-dimensional capacitors for the terabyte ferroelectric random access memory.
