Pb(ZrxTi1–x)O3 (PZT) belt-type crystals, 50–150 μm long, 60–300 nm thick, and 1–2 μm wide, have been prepared on SrTiO3 monocrystal wafers using a novel method, where gold nanoparticles on a substrate confine the two-dimensional growth of the PZT. The microbelts formed have good prospects for application in micro/nanoelectromechanical systems and integrated optoelectronics.
