PLD-assisted VLS growth of aligned ferrite nanorods, nanowires, and nanobelts-synthesis, and properties

Article Abstract:

A systematic synthesis and characterization of aligned [alpha]-Fe2O3 (hematite), belongs to epsilon-Fe2O3 and Fe3O4 (magnetite) nanorods, nanobelts, and nanowires on alumina substrates is reported using pulsed laser deposition (PLD) method. The presence of spherical gold catalyst particles at the tips of the nanostructures indicates selective growth through the vapor-liquid-solid (VLS) mechanism.

Controlled growth of large-area, uniform, vertically aligned arrays of alpha-Fe2O3 nanobelts and nanowires

Article Abstract:

The study synthesized vertically aligned iron oxide nanobelt and nanowire arrays on a large-area surface by direct thermal oxidation of iron substrates under the flow of O2. It concluded that nanobelts are produced in the low-temperature region whereas cylindrical nanowires tens of nanometers thick are formed at relatively higher temperatures.
