Abstract: The formation of self-catalyzed and Au-catalyzed nanowires is studied theoretically within the nucleation limited regime. Within the model the nanowire composition is obtained as a function of liquid composition in the cases of nucleation at the triple phase line and central nucleation. We study the influence of the nucleus surface energy on the nanowire composition, varying temperature, Au concentration and group V concentration. We show that the compositional independence of the surface energy term is a good approximation comparing the results with exact calculations.

Keywords: modeling, nanowires, chemical composition, In$_x$Ga$_{1-x}$As, surface energy, critical nucleus.
