NER: Nanoparticle Synthesis and Assembly Induced by Laser Light

这项纳米级探索性研究(NER)项目的目标是开发一种通用方法，能够合成纳米颗粒并将其组装成扩展的规则、单一和交叉的线性阵列，并深入了解排列现象发生的原因。方法是结合两种主要技术：薄膜沉积和激光照射，以避免使用掩膜和最大限度地减少多步骤处理的方式。随着原子的沉积，激光将迫使它们以有序的线条连接成纳米颗粒。可以通过改变光线的入射角度来改变线之间的间距。开发一种用于产生和操纵纳米结构的处理方法是一项重大的进步，该方法简单、非常通用、非常快速，并且非常适合建造设备。它可能成为一个重要的工具，使纳米制造与现有技术相结合，用于许多应用。展望未来，生产和组装纳米粒子的强大而多样的手段的开发将鼓励设备的设计和测试。将大力实施研究和教育的整合，与田纳西大学的使命保持一致。具体的教育计划包括培训两名学生，一名研究生和一名本科生，利用最先进的设备和适当的科学方法，对工程应用领域的前沿材料进行重点研究。将开发一个网站，说明所进行的研究，以供教学和信息之用。

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.
