项目摘要

0954696SinhaThis CAREER project is aimed at tailoring phonon transport phenomena in nanostructures through the control of coherence and anharmonicity effects. Coherence-scale phenomena are prominent in, for example, field-effect transistors while anharmonicity affects transport at interfaces separating hard and soft matter. The long-term goal of this project is to enable and advance pertinent applications ranging from nanoelectronics to nanomedicine. Theoretical tools will be developed to analyze coherence effects, while novel experiments will be devised and conducted to probe the spectral properties of phonons participating in thermal transport at hard-soft interfaces.Intellectual Merit: A systematic investigation of the role of anharmonicity (in soft matter) and coherence (in hard matter) during thermal transport will be conducted. A phonon wave transport theory will be extended to include particle-like behavior to enable the prediction of thermal responses in sub-10 nanometer transistors. A novel time-resolved Raman scattering approach to experimentally probe temperature-dependent anharmonic shifts in the frequencies of macromolecules will also be developed, providing a means to gain insight into the anharmonic dynamics of phonons in soft matter. Broader Impacts: The project is aimed at developing a fundamental understanding of thermal transport in soft and hard matter, and across interfaces separating these materials. This understanding may lead to new pathways for developing small-scale transistors, discovering new cancer therapies, and creating novel energy harvesting thermoelectric materials. The education plan will motivate students at multiple levels to pursue careers and research in energy conversion and the thermal sciences. New laboratory experiences will be incorporated into undergraduate laboratory courses at the PI's institution. Likewise, a new graduate course in nanotransport will be developed. Teaching kits will be developed for K-12 teachers, and outreach will include summer camps to introduce energy conversion principles to high school girls.
这个CAREER项目旨在通过控制相干和非调和效应来调整纳米结构中的声子输运现象。相干尺度现象在场效应晶体管中尤为突出,而非谐性影响着硬物质和软物质分离界面的输运。该项目的长期目标是实现和推进从纳米电子学到纳米医学的相关应用。将开发理论工具来分析相干效应,同时将设计和进行新的实验来探测参与硬-软界面热输运的声子的光谱特性。智力优势:系统地研究热输运过程中非调和性(软物质)和相干性(硬物质)的作用。声子波输运理论将被扩展到包括类粒子行为,从而能够预测亚10纳米晶体管的热响应。一种新的时间分辨拉曼散射方法也将被开发出来,用于实验探测大分子频率中温度相关的非调和位移,为深入了解软物质中声子的非调和动力学提供了一种手段。更广泛的影响:该项目旨在发展对软物质和硬物质以及分离这些材料的界面的热传输的基本理解。这种理解可能会为开发小型晶体管、发现新的癌症疗法和创造新的能量收集热电材料带来新的途径。该教育计划将激励不同层次的学生从事能源转换和热科学方面的职业和研究。新的实验经验将被纳入PI所在机构的本科实验课程。同样,将开设纳米输运的新研究生课程。将为K-12教师开发教学工具包,并将包括向高中女生介绍能量转换原理的夏令营。
