CAREER: Growth Mechanism, Synthesis and Application of Semiconductor Nanocrystals

本项目的目的是研究胶体无机纳米晶体的合成和加工。无机纳米晶体是相应的块状晶体的碎片，其至少一个维度在1至数十纳米的范围内。通过对半导体纳米晶体生长过程的系统和定量研究，为所有类型的胶体纳米晶体设计了一个完全可控的合成方案。 最终目标是开发安全、可靠、完全可控（尺寸、形态和分布）和定量可编程的高质量胶体纳米晶体合成化学。本课程将着重于成长机制的基础研究，以及发展绿色化学方法来合成高品质的半导体奈米晶体。尽管这个国家在不久的将来需要大量的纳米科学家和纳米工程师，但大多数大学目前的课程还没有反映出这种迫切的需求。教学计划的目的就是满足这一需要。这一理念将被纳入常规课程，以及新课程的开发，如材料化学，重点是纳米材料和纳米纤维。 胶体无机纳米晶体由于其显著的尺寸依赖性、优异的加工性和高比表面积而在基础研究和工业应用中引起极大的兴趣。这个综合性很好的研究和教育项目解决了目前对大量纳米科学家和纳米工程师的需求，这些科学家和工程师将在工业高度优先的领域接受培训。

The aim of this project is to study the synthesis and processing of colloidal inorganic nanocrystals. Inorganic nanocrystals are fragments of corresponding bulk crystals with at least one dimension in the range of one to tens of nanometers. A fully controllable synthetic scheme will be designed for all types of colloidal nanocrystals by focusing on a systematic and quantitative study of the growth process of semiconductor nanocrystals. The ultimate goal is to develop safe, reliable, fully controllable (size, morphology and distribution), and quantitatively programmable synthetic chemistry for high quality colloidal nanocrystals. A fundamental study of growth mechanisms together with the development of a green chemistry approach to synthesizing high quality semiconductor nanocrystals will be emphasized. Even though this country will need a large number of nano-scientists and nano-engineers in the near future, the current curricula in most universities have not yet reflected this urgent demand. The aim of the teaching plan is to address this need. This philosophy will be incorporated into regular courses to be taught as well as the development of new courses such as materials chemistry with a strong emphasis on nanomaterials and nanofabrication. %%%Colloidal inorganic nanocrystals are of great interest for both fundamental research and industrial applications because of their phenomenal size dependent properties, excellent processibility, and high specific surface area. This well integrated research and education project addresses current needs for a large number of nano-scientists and nano-engineers to be trained in areas of high priority to industry.***
