Publikováno v: Nanotechnology. 33:495301
The self-ordered anodic aluminium oxide (AAO) structure consists of micron-scale domains—defect-free areas with a hexagonal arrangement of pores. A substantial increase in domain size is possible solely by pre-patterning the aluminium surface in th

Study of quasi-two- and three-dimensional ordered porous structures by means of small-angle X-ray scattering in the grazing incidence geometry
Autor: N. A. Grigoryeva, A. A. Mistonov, Sergey V. Grigoriev, I. S. Dubitskiy, G. A. Valkovskiy, N. A. Sapoletova
Publikováno v: Physics of the Solid State. 59:2464-2475
The structure of surface layers of thin metal inverse opals has been studied first by the grazing-incidence small-angle X-ray scattering technique. Contributions of the form factor and structure factor to the small-angle diffraction pattern have been

Polarization-enhanced cell walls etching of anodic titanium oxide
Autor: Kirill S. Napolskii, S. E. Kushnir, N. A. Sapoletova
Publikováno v: Nanotechnology. 33:065602
Anodic titanium oxide (ATO) photonic crystals (PhCs) are promising for photonics, photocatalysis, and solar cells. A refractive index modulation in ATO PhCs is caused by the modulation of porosity and, thus, the pore diameter should be controlled pre
