Multiplicity of steady modes of nanowire growth

Abstract

For nanowire growth by the vapor-liquid-solid process, we examine whether there is a unique steady-state growth morphology. Applying a continuum model for faceted nanowire evolution to a model crystal structure, we enumerate the possible growth morphologies and calculate their dynamical stability. We find that even for a single set of experimental conditions there can be multiple distinct modes of steady-state growth. The actual growth mode occurring in experiment thus depends on the initial conditions and growth history. Relevant experiments are discussed. © 2012 American Chemical Society.
