摘要:
InN nanorods with polyhedral ends were grown by evaporating indium in the flow of ammonia gas on Si substrates coated with An catalyst. The samples were characterized by scanning electron microscopy, transmission electron microscopy (TEM), and X-ray diffraction (XRD). XRD shows that the samples contain both cubic and hexagonal phases. From the TEM results, it can be found that the cubic nanorods grow along [010] direction with a lattice constant of 0.497 nm, while the hexagonal nanotods grow along [010] direction. The growth mechanism of the obtained nanostructures is discussed. (c) 2006 Elsevier B.V. All rights reserved.
