NER: Nanoparticle Synthesis and Assembly Induced by Laser Light

这个纳米级探索性研究（NER）项目的目的是开发一种通用方法，能够合成纳米粒子并将其组装成扩展的规则，单一和交叉的线性阵列，并深入了解为什么会发生对齐现象。该方法是联合收割机的两个主要技术：薄膜沉积和激光照射，在设计的方式，以避免使用掩模，并尽量减少多步处理。 当原子沉积时，激光将迫使它们以有序的线条结合成纳米颗粒。线之间的间距可以通过改变光的入射角来改变。开发一种简单、非常通用、非常快速且非常适合构建器件的用于生成和操纵纳米结构的处理方法代表了一个重大进步。它可以成为一个重要的工具，使纳米制造与现有技术的集成，为许多应用。有远见的是，生产和组装纳米粒子的强大而多功能的方法的发展将鼓励设备的设计和测试。 研究和教育的整合将得到大力实施，与田纳西大学的使命相协调。具体的教育规划包括培训两名学生，一名研究生和一名本科生，使用最先进的设备和适当的科学方法对工程应用前沿的材料进行重点研究。 将建立一个网站，介绍所进行的研究，以供指导和参考。

The object of this Nanoscale Exploratory Research (NER) project is to develop a general method capable of synthesizing nanoparticles and assembling them into extended regular, single and crossed, linear arrays, and to gain insight into why the alignment phenomenon takes place. The approach is to combine two main techniques: thin film deposition and laser irradiation, in a manner designed to avoid the use of masks and minimize multi-step processing. As the atoms are being deposited, laser light will force them to joint into nanoparticles in well ordered lines. The spacing between lines can be changed by changing the angle of incidence of the light. The development of a processing method for generating and manipulating nanostructures that is simple, very general, very fast and well suited for building devices represents a significant advance. It could become an important tool to enable the integration of nanoscale manufacturing with existing technologies, for many applications. In foresight, the development of powerful and versatile means for producing and assembling nanoparticles will encourage the design and testing of devices. The integration of research and education will be strongly implemented, in harmony with the mission of the University of Tennessee. The specific educational planning includes the training of two students, one graduate and one undergraduate, to conduct focused research on materials in the forefront of engineering applications using state-of-the-art equipment and appropriate scientific methodology. A web site will be developed where the research performed will be described for instructional and information purposes.
