Abstract

We report a template-directed growth of Pb(Zrx,Ti 1-x)O3 (PZT) nanotubes in conjunction with sol-gel process and spin coating technique and its shape modification with an electron-beam (e-beam) irradiation. Field emission scanning electron microscope (FESEM) and field emission transmission electron microscope (FETEM) images show that PZT nanotubes are successfully synthesized. Their outer diameters and lengths are estimated to be 50 nm and several micrometers, respectively. PZT nanotubes exhibit a high aspect-ratio (up to 400) with diameters of 50 nm and lengths of 20 μm. The occurrence of electron diffraction ring patterns confirms that the typical PZT nanotubes are polycrystalline. The high-intensity e-beam is used to modify the shape of a PZT nanotube forming a nanohook. FETEM images of the nanohook formation process shows that the e-beam irradiation can be used to form the PZT nanotubes into desired shapes.
