Vertically aligned boron nanowires in self-assembled large-scale arrays with excellent uniformity and high density have been fabricated using radio-frequency magnetron sputtering of boron and B2O3 powder onto various substrates. The nanowires thus produced are several tens of micrometers long and 20–80 nm wide, with typically platform-shaped tips (see Figure for a high-magnification SEM image).
