Ni₃Se₄/ZnSe Heterostructured Nanowires Grown by Molecular Beam Epitaxy

Ni3Se4/ZnSe heterostructured nano­wires with a sharp interface are fabricated using nanocatalysts generated on an annealed Au/Ni/ZnSe trilayer. The top Ni3Se4 section acts as an efficient catalyst to assist ultrafast growth of the bottom ZnSe section. A greater understanding of how the effective area and size of the catalyst affect the growth rate and preferred axial orientation of ultrathin nanowires is obtained.
