摘要：产生、感知和控制光的光电器件是现代信息技术时代的基础。社会越来越依赖这些设备来实现高效照明、信息显示和光数据传输。此外，光电子学的研究使新技术成为可能，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，这些技术有望使计算能力呈指数级增长，并使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的进步，以及将不同材料集成到功能光电子器件和系统中。这个科学技术中心，即现代光电材料按需集成中心（IMOD），正在开发基于溶液加工无机材料的新型光电材料、器件和系统，具有前所未有的功能。IMOD旨在通过建立学术团队与工业和国家实验室合作伙伴之间的密切关系，确保这些科学和技术进步成功转化为美国工业，同时以综合方式培养不同的科学家和工程师群体，重点是建立团队科学，包容性指导，沟通，各级技能。技术摘要：该STC的目标是推进原子精确合成科学，以实现具有合成化学精确性和增材制造可扩展性的胶体发射器。通过控制这些纳米材料的表面及其在小簇中的位置，现代光电材料随需应变集成中心（IMOD）试图解决纳米晶体构建块的紧急特性，这些组件表现出集体行为，如相干电荷、自旋和能量输运。与此同时，IMOD寻求研究和推进应用范围，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（量子位）和量子传感器，在电磁频谱上运行。因此，IMOD寻求克服稳定性、线宽和退相干方面的障碍，同时解决分散性、处理和设备架构。为了实现这些目标，IMOD围绕三个协同研究主题进行组织：(1)原子精确合成，包括II-VI， III-V， IV-VI和金属卤化物钙钛矿半导体的合成，掺杂剂和自旋中心的掺入，以及完美外延壳的生长；(2)异质集成和经典器件，包括将多个原子精密材料组合成单个结构或器件以实现新功能，同时寻求led和探测器等先进应用；(3)量子光电子学：解决(1)和(2)中开发的材料和组件的量子光和自旋特性；开发新型量子光源，探索非线性量子光学、空腔量子电动力学、极化电子学等前沿概念；并开发了一类新的基于胶体的量子比特。选择IMOD的技术成果是因为它们对具有重要经济和国家安全影响的行业具有更广泛影响的潜力。IMOD的更广泛的影响目标包括通过以下方式发展一支能够吸引所有美国人的stem能力的劳动力队伍：(1)以跨传统学科接口的综合团队方式培训多样化的科学家和工程师群体，从而确保美国劳动力能够领导国家的经济和技术发展；(2)为公众提供以科学和公平为重点的外展课程，同时使不同的参与者能够在包容的环境中学习STEM学科；(3)通过IMOD与工业和国家实验室的伙伴关系和规划加速知识转移。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值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.
