Simultaneous Growth of Pure Hyperbranched Zn₃As₂ Structures and Long Ga₂O₃ Nanowires

Through a facile and highly repeatable chemical vapor method, pure three-dimensional hyperbranched Zn₃As₂ structures and ultralong Ga₂O₃ nanowires were simultaneously grown with controllable locations in the same experiment. The hyperbranched Zn₃As₂ consists of cone-shaped submicro-/nanowires and has a single-crystalline tetragonal structure. This is the first report of nano Zn₃As₂ and hyperbranched Zn₃As₂ structures. The as-grown Ga₂O₃ nanowires are monoclinic single crystals. A vapor−solid−solid mechanism is suggested for the growth of the Ga₂O₃ nanowires, and a vapor-solid mechanism, for the Zn₃As₂ structures.
