Flow-Enabled Ordered Nanocrystal Assemblies

该项目的目的是开发一种简单但稳健的流动使能自组装（FESA）方法，该方法通过使用具有固定上板和移动下基板的两平行板几何结构来在由功能纳米晶体组成的大面积上可重复地产生高度有序的结构（即，量子点和量子棒）和二嵌段共聚物。将合成具有精确可控的尺寸、形状和表面特性的发光纳米晶体。随后，通过微观尺度的FESA和纳米尺度的自发自组装之间的协同作用，将获得由大面积纳米晶体组成的分级有序结构。将开发该过程的理论模型，并将其用作优化该过程的指导。在这个项目中产生的知识可能会导致创建和开发有趣的纳米器件和材料用于微电子，光电子，传感器和生物技术。该项目除了为本科生和研究生提供研究培训外，还将为高中教师提供暑期研究机会。

1332780LinThe objective of this project is to develop a simple, yet robust, flow-enabled self-assembly (FESA) method through the use of two-parallel-plate geometry with a fixed upper plate and a moving lower substrate to reproducibly create highly ordered structures over large areas composed of functional nanocrystals (i.e., quantum dots and quantum rods) and diblock copolymers. Luminescent nanocrystals with precisely controllable size, shape, and surface characteristics will be synthesized. Subsequently, hierarchically ordered structures composed of nanocrystals over large areas will be obtained via the synergy between FESA at the microscopic scale and spontaneous self-assembly at the nanoscale. A theoretical model of the process will be developed and used as a guide for optimizing the process. Knowledge generated in this project may lead to the creation and development of intriguing nanodevices and materials for use in microelectronics, optoelectronics, sensors, and biotechnology. The project will also offer summer research opportunities for high school teachers in addition to providing research training to undergraduate and graduate students.
