Growth habits and defects in ZnO nanowires grown on GaN/sapphire substrates

August 31, 2005
Author(s)
Igor Levin, Albert Davydov, Babak Nikoobakht, Norman Sanford, Pavel Mogilevsky
Growth habits and defects in epitaxial ZnO nanowires grown from Au catalyst on (00.1) GaN/sapphire substrate using the vapor-liquid-solid (VLS) technique were studied using electron microscopy and x-ray diffraction. The results revealed presence of both

Horizontal Growth and In Situ Assembly of Oriented Zinc Oxide Nanowires

Babak Nikoobakht, Chris A. Michaels, Stephan J. Stranick, Mark D. Vaudin
The positioning and directed assembly of semiconductor nanowires (NWs) is of considerable current interest for bottom-up approaches to the engineering of intricate structures from nanoscale building blocks. We report a horizontal growth mode for ZnO NWs on

Controlling The Growth Direction of ZnO Nanowires (NWs) on c and a -Plane Sapphire

February 1, 2004
Author(s)
Babak Nikoobakht, Albert Davydov, Stephan J. Stranick
The issue of controlling the growth direction of NWs is vital in nanotechnology applications and future optoelectronic devices. In an effort to address the above, we have begun studies aimed at selectively controlling the growth direction of horizontal
