We report first of its kind results with synthesis of III-antimonide nanowires, i.e., antimony (Sb) droplets can self-catalyze the growth of III-antimonide nanowires. Extensive experiments are conducted with GaSb system. This is a significant result in that one can actually use the same type of droplets (Sb in this case) to synthesize heterostructures involving different III-Sb compounds such as GaSb/InSb, etc. In addition, the use of Sb for tip led growth of nanowires could be advantageous for many other III-V compounds.
