Wires grown using
zinc acetate in trioctylamine have been doped with transition
metals (cobalt, manganese, iron, and copper) with an
emphasis on cobalt-doped wires. Cobalt-doped wires have
been characterized by SEM, TEM, PL, X-ray diffraction
(XRD), and electron paramagnetic resonance (EPR) to verify
doping uniformity and to investigate their magnetic properties.
Additionally, we will discuss a method of producing
vertical nanowire arrays from substrates coated with ZnO
seeds that are aligned with their c axes normal to the
surface.
