Dependence of the growth rate of nanowires on the nanowire diameter

摘要

The dependence of the rate G of nucleation-mediated growth of nanowires on the nanowire diameter D is considered. It is shown that an existing general formula for this dependence allows experimental determination of the nucleation rate and growth constant of the two-dimensional islands on the nanowire tip. Comparison with available G(D) data for GaAs nanowires demonstrates agreement between theory and experiment.
