Effects of three-dimensional Ehrlich-Schwoebel barrier on texture selection during Cu nanorod growth

Abstract

This work explores the effectiveness of the three-dimensional Ehrlich-Schwoebel (3D ES) barrier in the selection of textures during nanorod growth. The authors use molecular dynamics simulations to show that the 3D ES barrier, together with geometrical shadowing and the thermal dynamics of surface faceting, defines the texture of nanorods. The results offer insights into when and how the 3D ES barrier will be effective in texture selection, and may be applied to texture design during growth of various nanorods.
