Template-based surface nano-patterning to realize high performance devices — •Liaoyong Wen, Huaping Zhao, Fabian Grote, Yan Mi, Ranjith Vellacheri, Zhibin Zhan, Ahmed Al-Haddad, Yaoguo Fang, Kin Mun Wong, and Yong Lei — Fachgebiet 3D-Nanostrukturierung, Institut für Physik & ZIK MacroNano, Technische Universität Ilmenau, 98693 Ilmenau, Germany

Surface patterning using nano-templates are highly efficient in preparing large-scale ordered arrays of surface nanostructures. Here we introduce surface patterning processes using two templates that are prepared using self-assembly processes: ultra-thin alumina membranes (UTAMs) and monolayer polystyrene (PS) sphere arrays. The surface patterns have promising device applications due to the low-cost and time-saving fabrication processes of surface structures. The feature size of the building blocks of the surface patterns prepared using UTAM and PS templates can be adjusted from the quantum size to the nanometer size and to the micrometer size range. Different functional surface nano-patterns have been developed using the UTAM and PS templates, including 1D nanostructure arrays, quantum-sized nanodot arrays, and metallic hollow sphere arrays. The device applications in photocatalytic devices, supercapacitors, solar cells, SERS sensors, and field emission device will be demonstrated.
