In addition to advances in understanding of VLS NW growth and ternary phase diagrams for GaAs NW growth in the past years, an understanding of Au catalyzed GaAs NW shape (specifically facets) has also been achieved. The orientation and shape of NW facets determine the heterointerface of GaAs and hence its properties. Furthermore, Facet transformation has been reported as effecting growth rate and composition uniformity of NW shell during synthesis.\cite{Zheng_2013} A reuleauxtriangle with three [112] curved surfaces is determined to be the actual shape at the growth site instead of the previously believed hexagonal surface [111].The crystal structure is thermodynamically unstable and changes to [112] facets in a polarity-driven vapor solid growth mechanism that occurs simultaneously. When enough energy is supplied to overcome the activation barrier associated with facet change it can also adopt [110] facets. Jiang and coworkers developed a model based on the VLS nucleation theory to explain these findings.\cite{Jiang_2014}  HCl has been used in Au catalyzed GaAs NW growth to suppress wurtzite like crystal growth in favor zince blende crystal structure growth. The Chlorine interacts wit the Ga species to previen Ga to contribute to growth  Axial and radial growth are the two directions of growth taking place during nanowire growth for MOVPE and VLS. Radial growth occurs when species are absorbed on the sidewalls of the nanowire. It is possible for these species to be further absorbed towards the Au catalyst causing the toe be incorporated into the axial growth.
