Synthesis of antimony-based nanowires using the simple vapor deposition method.

III-V nanowires have attracted plenty of attention because of their potential outstanding performance in a wide range of applications. However, compared to other III-V nanowires, the synthesis of high quality Sb-based nanowires is less developed, which obstructs the progress towards further applications. In this study we report high quality GaSb and InSb nanowires synthesized by a simple vapor deposition method. Epitaxial growth of nanowires on growth substrates is demonstrated. Te doped GaSb nanowires are achieved through in situ doping during the vapor deposition process. Electrical measurements of nanowire field-effect transistors show high performance of the synthesized InSb nanowires.
