Generation of Electron Moiré Fringes on Designed Nanoporous Anodic Alumina Films and Their Replicated Ni Cone Arrays: Exploration of Domain Sizes and Nanopore Arrangements

摘要: Here, we demonstrate a new method to measure the domain sizes and periodicities of pore arrangements find boundaries in designed PAA film with conical nanopores. Such structural information can be simultaneously obtained by utilizing electron moire fringes without direct observation The are generated overlapping two patterns on basis principle traditional method. average size single domains is estimated about 2 mu m(2). Furthermore, Ni cone arrays successfully produced replication using film. Very clear visualized surface arrays. domain-shape domain-size observed almost similar those used as original template. This fact indicates that cones replicated under excellent electrochemical conditions.
