Two Methods of Calculation Ternary Nanowire Composition

Abstract

The growth of ternary nanowires via the vapor-liquid-solid mechanism is one of the possible ways of band gap engineering. However, the dependence of ternary nanowire composition on growth parameters is still unclear. We compare two theoretical approaches to ternary nanowire composition determined either by the formation of the critical island or by the step-flow growth of the monolayer. For typical parameters of gold-catalyzed growth, these two models give similar results. In the case of self-catalyzed growth, the step-determined model predicts higher In content in the NW than the island-determined.
