项目摘要
Over the past decade, a variety of nanomaterials have been synthesized as a result of intense research efforts. Now, it is very important to investigate collective behaviors/phenomena/interactions from a group of nanomaterials and find methodologies of maneuvering their extraordinary properties for the use of practical applications. Proposed research is to synthesize building blocks of various nanoparticle heterostructures and characterize transport properties of energy carriers such as electrons and phonons. Multi-dimensional nanomaterials including nanodots, nanowires, nanotubes, and nanosheets will be mixed to form films and bulk materials. In addition, the junctions and surfaces of such nanomaterials will be systematically altered for investigating the influence of modifications. The chemistry and methodologie for modifying nanomaterials, which is of great importance for building functional materials, will be intensively explored. This study will reveal key knowledge and understanding for developing and designing practical bulk-scale applications as well as provide profound understanding of carrier transport phenomena across nanoscale contacts/junctions/interfaces, which have not been extensively studied, but are of great importance in nanomaterials. Studying collective behaviors of nanomaterials is very transformative because nanomaterials need to be combined to build function materials for a practical use. Furthermore, this study offer fundamentals that are essential for many charge/heat transport related applications including thermoelectric and photovoltaic energy conversion, electronics, thermal management, and sensors. Research outcomes have been or will be integrated into core undergraduate courses, a new graduate course for undergraduate/graduate students as well as research/education programs for 6-12/undergraduate/graduate students and teachers.
在过去的十年中,由于大量的研究工作,已经合成了各种纳米材料。现在,研究一组纳米材料的集体行为/现象/相互作用,并找到操纵其特殊性质的方法以用于实际应用是非常重要的。拟议的研究是合成各种纳米颗粒异质结构的构建块,并表征电子和声子等能量载体的传输特性。包括纳米点、纳米线、纳米管和纳米片的多维纳米材料将被混合以形成膜和块体材料。此外,这种纳米材料的连接点和表面将被系统地改变,以研究修饰的影响。纳米材料的化学改性和方法学,这是非常重要的功能材料的建设,将深入探讨。这项研究将揭示开发和设计实际的大规模应用的关键知识和理解,以及提供跨纳米级接触/结/界面的载流子输运现象的深刻理解,这些现象尚未得到广泛研究,但在纳米材料中非常重要。研究纳米材料的集体行为是非常具有变革性的,因为纳米材料需要结合起来构建实用的功能材料。此外,这项研究提供了许多电荷/热传输相关应用,包括热电和光伏能量转换,电子,热管理和传感器的基本原理。研究成果已经或将被纳入核心本科课程,本科/研究生的新研究生课程以及6-12/本科/研究生和教师的研究/教育课程。
