We derive an analytic expression for the composition of a ternary solid material nucleating from a quaternary liquid melt. The calculations are based on the two-component nucleation theory with realistic descriptions of the liquid and solid phases. We apply this theory to gold-catalyzed, nucleation limited vapor–liquid–solid growth of ternary III–V nanowires. We consider ternary gallium, indium, and aluminum arsenides and antimonides and discuss growth conditions for optimum composition control in these materials. Furthermore, we compare our calculations with the results of an equilibrium thermodynamic model.

由季金基液态合金形成的III-V纳米三元纳米线的成核作用有限†

我们推导了从四元液态熔体成核的三元固体材料组成的解析表达式。该计算基于两组分成核理论，对液相和固相进行了实际描述。我们将这一理论应用于金催化的，成核作用受限的三元至五元纳米线的汽液固固增长。我们考虑了三价镓，铟和铝的砷化物和锑化物，并讨论了控制这些材料最佳组成的生长条件。此外，我们将计算结果与平衡热力学模型的结果进行了比较。
