Self-organization of porous anodic alumina films studied in situ by grazing-incidence transmission small-angle X-ray scattering.

ABSTRACT: Self-ordered porous anodic alumina (PAA) films are studied extensively due to a large number of possible applications in nanotechnology and low cost of production. Whereas empirical relationships between growth conditions and produced oxides have been established, fundamental aspects regarding pore formation and self-organization are still under debate. We present in situ structural studies of PAA films using grazing-incidence transmission small-angle X-ray scattering. We have considered the two most used recipes where the pores self-organize: 0.3 M H₂SO₄ at 25 V and 0.3 M C₂H₂O₄ at 40 V. During anodization we have followed the evolution of the structural parameters: average interpore distance, length of ordered pores domains, a
