Multiple nanostructures based on anodized aluminium oxide templates — •Yong Lei — Institut für Physik & IMN MacroNano (ZIK), Technische Universität Ilmenau, 98693, Ilmenau, Germany

New physical phenomena and superior properties in solids usually involve couplings of adjacent materials and architectures in nano-scale. Binary nanostructure arrays, capable of introducing intimate interactions between different sub-component arrays, could raise a new horizon of nanotechnology. Here we proposed a concept to achieve diverse binary nanostructure arrays with high degrees of controllability for each of the sub-components, including material, dimension, and morphology. This binary nano-structuring concept originates from a distinctive binary-pore anodic aluminum oxide template that possesses two dissimilar sets of pores in one matrix. Moreover, the binary-pore template is evolvable to multi-pore (ternary and quadruple) templates with higher pore densities and more morphologic options. Binary nanostructure arrays with different material and morphology combinations were explored, and shall lead towards applications such as in catalysis, energy conversion and magnetic devices.
