Systematic investigation of growth of InP nanowires by metalorganic vapor-phase epitaxy

The behavior of the vapor–liquid–solid growth of InP nanowires on (1 1 1)B oriented InP substrates by metalorganic vapor-phase epitaxial technique has been reported in details. The nanowires were grown using the colloidal Au nanoparticles as the seed to control their diameter in the nanometer scale. The grown nanowires were found to be very uniform in cross section along their longitudinal axis, closely spaced and aligned vertically on the substrate surface. The growth behavior of the nanowires and the sensitive growth and anneal temperature dependence on the stability of the nanowires have been discussed in details.
