Fabrication of Ni2In3 alloy nanotubes

Alloy nanotubes were successfully grown by self-organization. They were produced by annealing of carbon–nickel–indium mixture thin films that were prepared by pulsed laser deposition. The morphology was observed and analysed by both scanning and transmission electron microscopes. The diameters were tens of nanometres and the aspect ratios were more than 2500. The growth is suggested to be due to the driving force that originated from supersaturation of alloying liquid indium with solid nickel.
