      abstract     = {In this work we demonstrate experimentally the dependence
                      of InSb crystal structure on the ratio of Sb to In atoms at
                      the growth front. Epitaxial InSb wires are grown by a
                      self-seeded particle assisted growth technique on several
                      different III-V substrates. Detailed investigations of
                      growth parameters and post-growth energy dispersive x-ray
                      spectroscopy indicate that the seed particles initially
                      consist of In and incorporate up to $20 at.\%$ Sb during
                      growth. By applying this technique we demonstrate the
                      formation of zinc-blende, 4H and wurtzite structure in the
                      InSb wires (identified by transmission electron microscopy
                      and synchrotron x-ray diffraction), and correlate this
                      sequential change in crystal structure to the increasing
                      Sb/In ratio at the particle-wire interface. The low ionicity
                      of InSb and the large diameter of the wire structures
                      studied in this work are entirely outside the parameters for
                      which polytype formation is predicted by current models of
                      particle seeded wire growth, suggesting that the V/III ratio
                      at the interface determines crystal structure in a manner
                      well beyond current understanding. These results therefore
                      provide important insight into the relationship between the
                      particle composition and the crystal structure, and
                      demonstrate the potential to selectively tune the crystal
                      structure in other III-V compound materials as well.},
