A central challenge for contemporary nanotechnology is the production of functional nanodevices in a reproducible and parallel way by employing cost-efficient bottom-up methods. In order to accomplish this goal, ferroelectric templates are well suited, allowing for the controlled nanostructure self-assembly by the method known as "Ferroelectric Lithography" (FE-Litho).In FE-Litho, ferroelectric domain patterns direct the deposition of the nanostructures of your choice to the ferroelectric (FE) template. Since FE domains can be arbitrarily patterned with high accuracy over a broad size-range from nanometers to centimeters, FE-Litho not only is applicable for this bottom-up nano-engineering but, furthermore, excellently bridges the nano- to the macroscopic world with respect to integration and functionality.Lithium niobate (LiNbO3, LNO) is well suited as the FE template of our choice, since photochemical deposition of any species from the liquid phase is confined to adsorption to the ferroelectric domain wall (DW), only. Moreover, these 180° DWs in LNO measure less than 10 nm in width thus confining the deposition to a clearly defined nano-space.The first goal of this project hence is to make use of this challenging FE-Litho technique in order to build-up functional nanodevices, e.g. field effect transistors, bio assays, and coaxial nanocables, by employing carbon nanotubes (CNT), biological DNA molecules, and noble-metal nanowires as the building blocks, respectively. Our second goal is the thorough and fundamental investigation of the physical and chemical driving forces leading to this DW decoration process on LNO surfaces, which to date is still unclear.To achieve these aims, we plan to set up an in-situ and fully automated FE-Litho assembly platform based on a liquid-flow-cell including a scanning force microscope (AFM) mounted on top of an inverted UV-optical microscope. This setup then is used to accomplish all the preparation steps (e.g. UV-induced domain engineering, photochemical DW decoration, CNT sorting and deposition under laminar flow) as well as to perform the in-situ characterization using advanced AFM modes such as conductive AFM, piezo-response and Kelvin probe force microscopy.

当代纳米技术的一个核心挑战是通过采用具有成本效益的自下而上的方法，以可重复和并行的方式生产功能纳米设备。为了实现这一目标，铁电模板是非常合适的，允许通过被称为铁电光刻(FE-Litho)的方法来控制纳米结构的自组装。在FE-Litho中，铁电域图案将您选择的纳米结构直接沉积到铁电(FE)模板上。由于FE域可以在从纳米到厘米的大小范围内以高精度任意图案化，FE-Litho不仅适用于这种自下而上的纳米工程，而且在集成度和功能方面很好地连接了纳米和宏观世界。LiNbO_3(LiNbO_3，LNO)非常适合作为我们选择的FE模板，因为从液体中光化学沉积的任何物种都仅限于吸附到铁电磁畴壁(DW)。因此，本项目的第一个目标是利用这种具有挑战性的FE-Litho技术，通过分别使用碳纳米管(CNT)、生物DNA分子和贵金属纳米线作为构建块，构建功能纳米器件，例如场效应晶体管、生物分析和同轴纳米电缆。我们的第二个目标是深入和基础地研究导致LNO表面DW装饰过程的物理和化学驱动力，至今仍不清楚。为了实现这些目标，我们计划建立一个基于液体流动池的原位和全自动化FE-LTHO组装平台，包括安装在倒置紫外光显微镜上的扫描力显微镜(AFM)。然后使用该装置完成所有的制备步骤(例如，紫外诱导区工程、光化学DW修饰、碳纳米管分类和层流沉积)，以及使用先进的AFM模式(如导电AFM、压电响应和开尔文探针力显微镜)进行原位表征。
