大面积单晶结构阵列制备数据集

本数据集主要面向高密度、高集成度的智能有机半导体器件研究，针对大面积有机半导体单晶精确图案化加工中存在的技术瓶颈，如加工面积、分辨率、加工效率、加工成本、尺寸均匀度等，通过控制液体的定向退浸润就可以调节液体内部的剪切力方向，从而达到调控分子堆叠方式，最终实现控制晶体的定向生长。在微米级别上控制液膜的退浸润可以更加精确的控制分子排列的有序性和晶体生长的方向，从而实现一维单晶结构的规则化阵列。而这种规则化的一维单晶材料在未来作为微纳米电子器件方面具有很大潜力。因此，我们需要在控制溶液退浸润的基础上，同时将液体分割来实现我们的目的。通过采用带有微柱结构的硅片模板，经过选择性修饰后使其具有不对称浸润性，利用其去调控流体的退浸润过程和微结构组装过程。通过采用这种方法，可以使我们通过调控每个液桥的形成、定位、退浸润动力学过程来实现π共轭的共轭聚合物一维结构的排列和组装。由于分散液的退浸润过程受到了准确的调控，我们成功制备得到了位置准确、取向一致的有机一维结构阵列。本数据集是2018-2022年期间在中国科学院理化技术研究所仿生材料与界面科学院重点实验室完成的，主要记录了大面积有机阵列的宏观数码照片和微观显微照片，以及激光共聚焦显微镜、原子力显微镜等数据，以证明大面积有机阵列的尺寸均匀性较高。

This dataset is primarily developed for research on high-density, highly integrated intelligent organic semiconductor devices. Aiming at the technical bottlenecks in the precise patterning of large-area organic semiconductor single crystals, including processing area, resolution, processing efficiency, fabrication cost, and dimensional uniformity, we regulate the internal shear force direction of liquids via controlling directional dewetting, thereby modulating molecular stacking modes and ultimately achieving controlled oriented crystal growth. Controlling the dewetting of liquid films at the micrometer scale allows more precise control over the order of molecular arrangement and the direction of crystal growth, thus forming regular arrays of one-dimensional single-crystal structures. Such regular one-dimensional single-crystal materials exhibit great potential for future applications as micro-nano electronic devices. Therefore, we need to split the liquid while controlling solution dewetting to achieve our objectives. By utilizing silicon templates with micropillar structures, which are modified selectively to possess asymmetric wettability, we regulate the dewetting process of fluids and the assembly process of microstructures. With this approach, we can realize the arrangement and assembly of one-dimensional structures of π-conjugated polymers by modulating the formation, positioning, and dewetting kinetics of each liquid bridge. Owing to the precisely regulated dewetting process of the dispersion liquid, we successfully fabricated organic one-dimensional structure arrays that are accurately positioned and uniformly oriented. This dataset was constructed between 2018 and 2022 at the Key Laboratory of Bionic Materials and Interfaces, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences. It mainly records macroscopic digital photographs and microscopic images of large-area organic arrays, as well as characterization data from laser confocal microscopy, atomic force microscopy (AFM) and other related instruments, to verify the high dimensional uniformity of the large-area organic arrays.
