Title: DMREF/Collaborative Research: Development of Materials for On-Chip Silicon-Integrated Optical Communication Data transfer rates between silicon electronic chips are reaching a limit that prevents the continued development of high speed smart-phones, computers, and internet devices. While silicon?s properties are excellent for electronic devices, optical sources based on silicon are incapable of efficient, high-speed communication. Within the framework of the Materials Genome Initiative, this project will seek new materials and associated fabrication processes to overcome this hurdle. Recently it has been shown that MDC materials, such as molybdenum disulfide, can be grown in large-scale, high quality, atomically thin films on silicon dioxide substrates. Theoretically, it is predicted that such materials are semiconductors with a tunable, direct band gap that renders them far superior for optical communication applications than silicon. This research project intends to develop a theory-driven understanding of fabrication and control of such atomically-thin materials towards validating their use as on-chip light sources for future optical interconnects for integrated circuits. The PIs have an excellent track of record on promoting STEM activities within their respective institution. They intend to work with high school students, undergraduate and graduate students, and involve students from underrepresented groups in the planned research. The outreach activities proposed in this project are solid and will definitely have a broader societal impact.The goals of this project are to create a continuous knowledge link between atomistic material theory and chemical material synthesis of a variety of 2D metal dichalcogenidies and their alloys as a foundation for discovering, synthesizing, and accelerating the next generation of on-chip laser devices suitable for applications in telecommunication and data-processing. It builds on recent findings by the principal investigators such as strain-stabilization of different metaldichalcogenide phases, mm-scale growth of continuous single-layer molybdenum disulfide films, and loss management and demonstration of laser devices featuring optical mode sizes below the diffraction limit of light. The research collaborators will combine theoretical screening of a broad range of materials and predictive modeling of substrate stabilization of their structure, with development of growth methods for a diverse set of materials, and application-near functional evaluation on a waveguide tested. This project brings together an interdisciplinary set of methods ranging from analytical and numerical simulation, to chemical process development and the design and characterization of on-chip integrated laser devices. This vertical, theory-based integration of materials development methods realizes the goal of the Materials Genome Initiative. Success of this project will provide input to the field of functional 2D materials for years to come that will be instrumental in the development of novel photonic integrated circuits, and potentially sensors.

职务名称：DMREF/协作研究：硅电子芯片之间的数据传输速率正在达到极限，这阻碍了高速智能手机、计算机和互联网设备的持续发展。而硅？虽然硅的特性对于电子设备来说是极好的，但是基于硅的光源不能进行高效、高速的通信。在材料基因组计划的框架内，该项目将寻求新材料和相关的制造工艺来克服这一障碍。最近已经表明，MDC材料，如二硫化钼，可以在二氧化硅衬底上生长大规模，高质量，原子级薄膜。 从理论上讲，预计此类材料是具有可调直接带隙的半导体，这使得它们在光通信应用中比硅优越得多上级。该研究项目旨在开发一种理论驱动的理解这种原子级薄材料的制造和控制，以验证它们作为集成电路未来光学互连的片上光源的用途。PI在各自机构内促进STEM活动方面拥有良好的记录。他们打算与高中生、本科生和研究生合作，并让来自代表性不足群体的学生参与计划中的研究。本项目的目标是在原子材料理论和各种二维金属二硫属化物及其合金的化学材料合成之间建立一个连续的知识联系，作为发现、合成、并加速下一代适合于电信和数据处理应用的片上激光器件。它建立在主要研究人员最近发现的基础上，例如不同金属二硫属化物相的应变稳定、连续单层二硫化钼薄膜的毫米级生长，以及光学模式尺寸低于衍射极限的激光器件的损耗管理和演示。光。研究合作者将结合联合收割机的理论筛选范围广泛的材料和预测建模的基板稳定的结构，与发展的生长方法，为一组不同的材料，和应用近功能评估的波导测试。该项目汇集了一套跨学科的方法，从分析和数值模拟，到化学工艺开发以及片上集成激光器件的设计和表征。这种垂直的、基于理论的材料开发方法的整合实现了材料基因组计划的目标。该项目的成功将为未来几年的功能性2D材料领域提供投入，这将有助于开发新型光子集成电路和潜在的传感器。
