Abstract
Hysteresis in current and ferroelectric piezoelectric phase were collected across the walls of individual, electrically interfaced lead zirconate titanate (PZT) nanotubes. The nanotubes exhibit average on/off current ratios of similar to 10 and similar to 1000 in static local probe and top-electroded configurations, respectively. Reversibility in conduction state of an individual nanotube following different stages of an O(2)-rich/O(2)-deficient/O(2)-rich anneal cycle provide evidence of an oxygen vacancy concentration-based conduction mechanism.
