In-plane aligned Pb(ZrxTi1-x)O3 microbelts fabricated by near migration and restricted growth

Pb(ZrxTi1-x)O-3 (PZT) belt-type crystals, 50-150 mu m long, 60-300 nm thick, and 1-2 mu m 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.
