Abstract

Nanotechnology has attracted great attention as one of essential fields in modern science. In particular, the fabrication of nanostructures with nanometer dimension in size is the starting point and essential part of nanotechnology research. Anodic aluminum oxide (AAO) nanotemplate technique has many merits including ease of fabrication, low cost process, and nanotemplate fabrication in large area. Moreover, AAO nanotemplate technique can realize self-ordered hexagonal pore structure with extremely high aspect ratio which is difficult to achieve with conventional lithographic techniques. Simple control of pore dimensions such as diameter, length, and density by varying anodizing condition would be advantageous, too. AAO nanotemplate has been the topic of intensive investigations for the past decade due to above strong points, and the application to various fields of nanotechnology is expected. In this review paper, the fabrication and application of AAO nanotemplate are introduced.

나노 기술은 현대 과학에 있어서 가장 주목 받고 있는 분야이며, 특히 나노미터 크기의 디멘션(dimension)을 가지는 나노 구조물의 제작은 나노 기술 연구의 출발점이며, 핵심 요소이다. 양극산화 알루미나 나노 템플레이트(anodicaluminum oxide or AAO nanotemplate) 기술은 상대적으로 공정이 쉽고 경제적이며, 대면적으로 나노 템플레이트의 제작이 가능하다는 장점을 가지고 있다. 또한 현재의 리소그래피 기술로는 달성하기 어려운 수준의 매우 큰 종횡비(aspect ratio)를 가능하게 하고, 조건을 변화시킴에 따라서 나노 템플레이트 기공의 직경 및 길이, 기공 밀도의 조절이 용이하다는 장점을 가지고 있어서 최근 10여 년간 매우 활발하게 이와 관련된 연구가 진행되어 왔으며, 다양한 나노 기술 분야로의 응용이 기대된다. 본 총설에서는 양극산화 알루미나 나노 템플레이트의 제조 및 응용에 대해 기술하였다.
