非技术摘要：产生、感知和控制光的光电子器件是现代信息技术时代的基础。社会越来越依赖这样的设备来实现高效照明、信息显示和光学数据传输。此外，光电子学的研究正在使新技术成为可能，从无处不在的传感器和逼真的虚拟现实显示器，到基于量子的信息技术，这些技术有望带来计算能力的指数级增长，并确保通信网络免受黑客攻击。反过来，光电子学的这种进步越来越依赖于高精度材料合成方面的进步，以及伴随而来的不同材料与功能光电子器件和系统的集成。这个科技中心，即现代光电材料按需集成中心(IMOD)正在开发基于溶液处理无机材料的具有前所未有功能的新型光电材料、器件和系统。IMOD寻求通过在学术团队与工业和国家实验室合作伙伴之间建立密切的关系来确保这些科学和技术进步成功地转化为美国工业，同时以一种综合的方式培养不同的科学家和工程师群体，专注于在所有层面上建立团队科学、包容性指导和沟通技能。技术摘要：该STC的目标是促进原子精密合成的科学，以实现具有合成化学的精确度和添加剂制造的可扩展性的胶体发射器。通过控制这些纳米材料的表面和它们在小簇中的位置，现代光电材料按需集成中心(IMOD)寻求解决纳米晶构建块组件的紧急性质，这些组件表现出集体行为，如相干电荷、自旋和能量传输。与此同时，IMOD寻求研究和推进各种应用，从量子点发光二极管(QLED)和探测器，到新的量子光源、基于自旋的量子比特(Qbit)和跨电磁频谱运行的量子传感器。因此，IMOD试图克服稳定性、线宽和消相干方面的障碍，同时解决分散性、处理和设备架构问题。为了实现这些目标，IMOD围绕三个协同研究主题组织：(1)原子精密合成，包括II-VI、III-V、IV-VI和金属卤化物钙钛矿半导体的合成，掺杂和自旋中心的加入，以及完美外延壳层的生长；(2)异质集成和经典器件，包括将多种原子精密材料组合到单一结构或器件中，以实现新的功能，同时寻求推进LED和探测器等应用；以及，(3)量子光电子学：处理(1)和(2)中开发的材料和组件的量子光和自旋性质；同时开发一类新的量子光源，探索非线性量子光学、腔量子电动力学和极化电子学的前沿概念，并开发一类新的胶体量子比特。选择IMOD的技术成果是因为它们有可能对具有重要经济和国家安全影响的行业产生更广泛的影响。IMOD更广泛的影响目标包括发展一支有STEM能力的劳动力队伍，通过以下方式吸引所有美国人：(1)以跨传统学科界面的基于团队的综合方式培训不同的科学家和工程师群体，从而确保美国劳动力具备领导国家经济和技术发展的能力；(2)使公众能够接触到以科学和股权为重点的外展课程，同时使其不同的参与者能够在包容的环境中学习STEM学科；以及(3)通过IMOD与行业和国家实验室的合作伙伴关系和编程来加速知识转移。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Non-Technical Abstract: Optoelectronic devices that generate, sense, and control light underpin the modern information-technology era. Society is increasingly reliant on such devices for efficient lighting, information display, and optical data transmission. Furthermore, the study of optoelectronics is enabling new technologies ranging from ubiquitous sensors and photorealistic virtual reality displays to quantum-based information technologies that promise to produce exponential increases in computing power and secure communication networks from hacking. Such advances in optoelectronics, in turn, rely increasingly on advances in the synthesis of highly precise materials and the concomitant integration of different materials into functional optoelectronic devices and systems. This Science and Technology Center, the Center for Integration of Modern Optoelectronic Materials on Demand (IMOD) is developing new classes of optoelectronic materials, devices, and systems with unprecedented functionality based on solution-processed inorganic materials. IMOD seeks to ensure the successful translation of these scientific and technological advances to U.S. industries by forging close relationships between the academic team and industrial and national lab partners, while educating a diverse group of scientists and engineers in an integrated fashion that focuses on building team-science, inclusive mentoring, and communication, skills at all levels.Technical Abstract: This STC’s goal is to advance the science of atomically precise synthesis to achieve colloidal emitters with the exactness of synthetic chemistry, and the scalability of additive manufacturing. By controlling the surfaces of these nanomaterials, and their position in small clusters, the Center for Integration of Modern Optoelectronic Materials on Demand (IMOD) seeks to address emergent properties of assemblies of nanocrystalline building blocks that exhibit collective behavior such as coherent charge, spin, and energy transport. At the same time, IMOD seeks to study and advance applications ranging from quantum-dot light-emitting diodes (QLEDs) and detectors, to new quantum-light sources, spin-based quantum bits (qubits), and quantum sensors, operating across the electromagnetic spectrum. Thus, IMOD seeks to overcome barriers in stability, linewidths, and decoherence, while tackling dispersity, processing, and device architectures. To achieve these goals, IMOD is organized around three synergistic research themes: (1) Atomically precise synthesis, comprising synthesis of II-VI, III-V, IV-VI, and metal-halide perovskite semiconductors, incorporation of dopants and spin centers, and growth of perfect epitaxial shells; (2) Heterointegration and classical devices, including the combination of multiple atomically precise materials into a single structure or device to achieve new functionality, while seeking to advance applications like LEDs and detectors; and, (3) Quantum optoelectronics: addressing quantum light and spin properties of materials and assemblies developed in (1) and (2); while developing a new class of quantum light sources and exploring frontier concepts in non-linear quantum optics, cavity quantum electrodynamics, and polaritonics; and developing a new class of colloidal-based qubits. IMOD’s technology outcomes are chosen for their potential to have broader impacts on industries with important economic and national-security impacts. IMOD’s broader impact goals include development of a STEM-capable workforce that engages all Americans by: (1) training a diverse group of scientists and engineers in an integrated team-based fashion across traditional disciplinary interfaces, thus ensuring a U.S. workforce equipped to lead the Nation’s economic and technological development; (2) making science and equity-focused outreach curricula accessible to the public while empowering its diverse participants to pursue STEM disciplines in an inclusive environment; and (3) accelerating knowledge transfer through IMOD’s partnerships and programming with industry and national laboratories.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
