Nontechnical Description: Design and engineering the properties of matter at the atomic level is a new frontier in materials research that seeks to revolutionize applications employing quantum devices. Examples include electronic and optoelectronic devices with improved power and bandwidth performance, which can enable high performance electronics, photonics, and efficient communications. This vision has received a boost by the discovery of truly two-dimensional materials, such as graphene, metal dichalcogenides, boron nitride, and their combinations. These structures provide a compelling material platform for basic research and applications. Because the two-dimensional materials reach the ultimate limit of thinness, being essentially one atom thick, they require new ways of synthesis and assembly into practical devices and they offer new challenges to our understanding of fundamental and practical aspects of physics in two dimensions. This research team focuses on fundamental understanding of the science of atomically thin materials and their stacked structures, seeking discoveries of novel physical phenomena and exploring new device concepts. The team also works on education and outreach projects, supporting undergraduates and public school teachers. Through these research and educational projects, graduate students and undergraduates are educated in a highly interdisciplinary environment. The team also develops an active outreach partnership with the Museum of Science, Boston, to promote public awareness of science and technology at the nanoscale.Technical Description: The research focus of this interdisciplinary team is on the demonstration of new techniques for designing and assembling two-dimensional van der Waals heterostructures and the fundamental study of novel emergent properties of these quantum heterostructures. Through this research, scientists and engineers in this team develop characterization tools and innovate electronic, plasmonic and optical devices based on various quantum behaviors, such as resonant tunneling. They explore new modalities for tunable continuous-wave terahertz generation and gate-modulation of optical and optoelectronic properties. The research team also investigates the microscopic electronic and magnetic properties of atomically thin heterostructures and develops multi-scale modeling of layered heterostructure devices. The formation of interfaces of unconventional low-dimensional materials systems and engineering of their electronic, optoelectronic and magnetic properties, carried out by this interdisciplinary team, leads to new device paradigms.

非技术描述：在原子水平上设计和设计物质的特性是材料研究的一个新领域，旨在彻底改变量子设备的应用。例如，具有改进的功率和带宽性能的电子和光电设备，可以实现高性能电子学、光子学和高效通信。这一愿景因真正二维材料的发现而得到推动，例如石墨烯、金属二硫属化物、氮化硼及其组合。这些结构为基础研究和应用提供了一个引人注目的材料平台。由于二维材料达到了薄度的极限，基本上只有一个原子厚，因此需要新的合成方法和组装成实际器件，并且对我们理解二维物理的基础和实践方面提出了新的挑战。该研究团队专注于对原子薄材料及其堆叠结构科学的基本理解，寻求新奇物理现象的发现并探索新的设备概念。该团队还致力于教育和外展项目，为本科生和公立学校教师提供支持。通过这些研究和教育项目，研究生和本科生在高度跨学科的环境中接受教育。该团队还与波士顿科学博物馆建立了积极的外展合作伙伴关系，以提高公众对纳米级科学技术的认识。技术描述：这个跨学科团队的研究重点是展示设计和组装两种纳米粒子的新技术。维范德华异质结构以及这些量子异质结构的新颖涌现特性的基础研究。通过这项研究，该团队的科学家和工程师开发了表征工具，并基于各种量子行为（例如共振隧道效应）创新了电子、等离子体和光学器件。他们探索了可调谐连续波太赫兹产生以及光学和光电特性的栅极调制的新模式。研究小组还研究了原子薄异质结构的微观电子和磁性特性，并开发了层状异质结构器件的多尺度建模。由这个跨学科团队进行的非常规低维材料系统界面的形成及其电子、光电和磁性能的工程，导致了新的设备范例。
