21_29b/2009Nanotube Arrays: Morphology Control of Nanotube Arrays (Adv. Mater. 29/2009)

On p. 2983 Michael J. Brett and co-workers demonstrate a template-directed technique to produce arrays of silicon nanotubes (SiNTs) with highly engineerable morphology. Fabrication steps include glancing angle deposition (GLAD) of the templates, low-pressure CVD of a shell-Si coating, ion milling to expose the templates, and wet-chemical etching for removal of the templates. The technique may be generally adapted to a wide variety of morphologies and NT materials.
