Periodic nanometric superstructures for photonic applications

摘要

In this paper, we will introduce a non-lithographic technique that utilizes self-organized, highly ordered ariodized aluminum oxide (AAO) porous membrane as a template to form a variety of periodic nanometric superstructures. Materials as different as metals, semiconductors, and carbon nanotubes (CNT) can be adapted into this platform with equal ease. The flexibility with materials, the accurate control over the fabrication process, and the command over the alumina template attributes offers us a new degree of freedom of engineering various physical properties by templating the nanostructures with the desired shape, size, composition, and doping. The versatile nanometric superstructure platform realized by this unique approach can enable a broad range of applications including infrared detector and quantum dot lasers and so on.
