项目摘要
This project addresses basic issues of materials at nanoscale dimensions. The research will investigate thermodynamic properties of Si nanostructures and silicide interfaces using a new and highly sensitive calorimetric device. For example, the phenomenon of melting point depression for surface-supported particles can be measured for particles as small as 1000 atoms.The focus is on understanding unique properties and behavior of nanometer-sized materials. The approach is to measure thermodynamic properties of Si nanostructures and silicide interfaces including structural stability and heat capacity to establish a more complete picture of the material physics of structures at these dimensions. Earlier investigations of magic number(integers of atomic layers) nanostructures from metals to semiconductor Si nanostructures will be extended by measuring the specific heat, melting temperature, and associated enthalpy, as well as particle size using TEM. %%% The project addresses basic research issues in a contemporary topical area of materials science with high potential significance and technological relevance. An important feature of the program is the integration of research and education through the training of students in a fundamentally and technologically significant area. The project is expected to provide unique opportunities for graduate and undergraduate students to develop strong technical, communication, and organizational/management skills through unique experiences made possible by a forefront research environment.
这个项目解决了纳米尺度材料的基本问题。这项研究将使用一种新的高灵敏度的量热装置来研究硅纳米结构和硅化物界面的热力学性质。例如,表面支持的颗粒的熔点下降现象可以测量到小到1000个原子的颗粒。重点是了解纳米材料的独特性质和行为。该方法是测量硅纳米结构和硅化物界面的热力学性质,包括结构稳定性和热容,以建立在这些维度上结构的材料物理更完整的图景。早期对从金属到半导体硅纳米结构的魔数(原子层的整数)纳米结构的研究将通过测量比热、熔化温度和相关的热焓以及使用电子显微镜测量颗粒尺寸来扩展。该项目致力于当代材料科学热点领域的基础研究问题,具有很高的潜在意义和技术相关性。该计划的一个重要特点是通过在一个具有根本意义和技术意义的领域对学生进行培训,将研究和教育结合起来。该项目预计将为研究生和本科生提供独特的机会,通过前沿研究环境带来的独特体验,发展强大的技术、沟通和组织/管理技能。
