We observed the nanoscale retention dynamics of polycrystalline PbTiO{sub 3} nanotubes using piezoresponse force microscopy. We found that the retention loss of the nanodot domains on the nanotubes showed the stretched exponential relaxation behaviors with stretched exponential factor n being less than 1 (0.523 and 0.692), which are similar to the thin films. In addition, the nanodot domains showed a diverse relaxation time constant {tau} due to different remnant polarization of each dot domains.
