Growth Kinetics of Ultrathin ZnO Nanowires Grown by Pulsed Laser Deposition

Abstract Depending on the application nanowires have to fulfil different requirements, e.g. regarding their length and diameter. In order to adjust and control these properties during the nanowire growth, the understanding of the growth mechanism is important. Here we discuss the growth of ZnO nanowires by pulsed laser deposition and show, that the length and diameter of the deposited nanowires does not depend linearly on the deposited ZnO particles. From this finding we deduce that the lateral and vertical growth rate is changing with the total amount of deposited ZnO particles.
