Influence of elastic stresses on the vapor-solid-solid growth mechanism of Au-catalyzed GaAs nanowires

Year: 2018

Type: conference-paper

Abstract: Influence of elastic stresses on the vapor-solid-solid growth mechanism of Au-catalyzed GaAs nanowires is studied. The elastic energy of the triangle-shaped island formed on the catalyst-nanowire interface is calculated. It is shown that the nucleation time of the triangle-shaped island is several times higher than that of the disk-shaped island in the case of nucleation of semi-coherent islands. The contribution to the free energy of island formation from the formation of island side walls is higher for the triangle-shaped island, although, its contribution from the elastic energy is lower when islands nucleate at the catalyst free surface.
