Monodomain High‐Aspect‐Ratio 2D and 3D Ordered Porous Alumina Structures with Independently Controlled Pore Spacing and Diameter

Abstract

Ordered porous alumina with uniform as well as nanofunnel-shaped pore structures are fabricated by using interference lithography to template pore formation and to control the pore spacing, and by using electrolyte changes to independently control and vary the diameters of the pores.
