Realizing three-dimensional nanostructures using nano-templates: concept, properties and high performance devices — •Fabian Grote, Liaoyong Wen, Zhibing Zhan, Ahmed Al-Haddad, Yan Mi, Samar Tarish, Chengliang Wang, Ranjith Vellacheri, Huaping Zhao, and Yong Lei — Fachgebiet 3D-Nanostrukturierung, Institut für Physik & IMN MacroNano (ZIK), Technische Universität Ilmenau, Prof. Schmidt Str. 26, 98693 Ilmenau, Germany

Here we introduce a templates-based three-dimensional (3D) nano-structuring technique,[1,2] which has been utilized to fabricate diverse functional 3D nanostructures in our group, including highly ordered arrays of nanowires, nanotubes, core-shell and heterojunction nanowire and tubes. Due to the well-defined structures of nano-porous templates, the structural parameters of the prepared 3D nanostructures can be precisely controlled, such as size, length, spacing and tube thickness. The fabrication processes of the proposed 3D nano-structuring technique is highly cost-effective for preparing large-area of nanostructure arrays, which is desirable for device applications. So far different devices have been constructed based on these 3D nanostructures including supercapacitors, sensors, catalysts and solar cells. The high performance of these devices confirms that this innovative 3D nano-structuring technique is the key to realize the next generation of functional nano-devices. Reference: [1] Y. Lei, S.
