This book was released on 2004 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the drive from microfabrication to nanofabrication, porous alumina templates may play a key role in technological evolution. Under the right processing conditions, ordered pores can grow in anodic aluminum oxide, which is a high strength, thermally and electrically insulating material. There are many potential applications for porous alumina templates, ranging from the simple fabrication of nanostructure arrays to the more complex processing of components for end-user products such as nano-integrated circuits and gas sensors. Porous alumina templates can also be processed to have long-range pore ordering on an entire twelve-inch silicon wafer, which may be of unique benefit to processes requiring such pore precision, such as parallel electron beam lithography. The high aspect ratios which can be attained through porous alumina template technology may also offer unique advantages in applications such as field-emission-based devices. As a durable high strength material, porous alumina templates are not limited by extreme process conditions, further extending the reach of their application. The vast array of applications allows the technology to be financially attractive inside business models ranging from sustaining to disruptive innovation. Porous alumina template technology has the necessary multitude and diversity of attributes to play a crucial role in the future of nanotechnology.

Abstract: Self-ordered anodic porous alumina with a nano-honeycomb structure has recently been extensively used as templates for the synthesis of various nanomaterials for diverse applications. However, due to the insufficient knowledge on the combined electro-chemo-mechanical processes, the formation mechanism of self-ordering has been under debate for decades without clear conclusions. Also, fast fabrication of highly self-ordered and mechanically stable anodic porous alumina is still a challenge. Furthermore, the actuation behavior of anodic porous alumina upon external mechanical and electrical triggering in an electrochemical cell has not been exploited. In this work, firstly, we investigated the self-ordering mechanism by establishing a kinetics model involving the Laplacian electric potential distribution and a continuity equation for current density within the oxide body. Current densities governed by the Cabrera-Mott equation are formed by ion migration within the oxide as well as across the interfaces. The pore channel growth, due to electric-field-assisted reactions, is governed by Faraday's law. Real-time evolution of pre-patterned pore channel growth was simulated in two-dimensional cases by finite element method. The simulations revealed a parameter domain within which pre-patterned pore channels will continue to grow in a stable manner during the subsequent anodization if the pre-patterns are commensurate with the self-ordered configurations, or these are driven into stable if the pre-patterns do not initially match the self-ordered configurations. This was verified in experimentally observed pore channel growth under the guidance of pre-patterns made by focused-ion-beam milling. Furthermore, the simulations revealed that ionization reaction on (001) oriented Al grain is relatively easier than that on (101) grain, which results in stable and unstable pore channel growth on (001) and (101) Al grains, respectively, both of which were observed from the simulations and experiments. Secondly, a scheme on quantitative evaluation of self-ordering qualities in anodic porous alumina has been developed, based on which we systematically searched the optimum self-ordering conditions, by varying the key anodization factors, including substrate grain orientation, electrolyte concentration, temperature, voltage, and time. A high acid concentration and high temperature anodization method was found. Compared with conventional methods, the present method can realize fast formation of highly self-ordered, and mechanically stable anodic porous alumina under a continuous range of anodization voltage with tunable interpore distances. Thirdly, reversible bending was found in anodic porous alumina-Al composites upon cyclic electric actuation, as directly observed by an optical microscope and detected by in situ nanoindentation. The bending is thought to be the result of charge-induced surface stresses in the nanoporous alumina. The results suggest a new type of composite materials for applications as micro-scale actuators to transform electrical energy into mechanical energy. Furthermore, the composite exhibits significant softening during in situ nanoindentation when the estimated maximum stress underneath the indenter is exerted on the metal/oxide interface. Softening was further verified by in situ microindentation. Electron microscopy examination indicated that the softeni
