Nanopores: A Novel Self‐Ordered Sub‐10 nm Nanopore Template for Nanotechnology (Adv. Mater. 37/2012)

Abstract

A wafer scale self-ordered array of high aspect ratio alumina nanopores with low porosity is obtained by anodization of aluminum. On page 5094, Margit Hanbücken, Eric Moyen, and co-workers show how the understanding of alumina pore nucleation enables the pore diameter control down to less than 10 nm. Such a material can be used as a template to fabricate sub-10 nm zero- and one-dimensional objects of a wide range of materials, meeting challenging applications in magnetic read heads or electrical DNA sequencing.
