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.

标题：DMREF/协作研究：开发芯片硅的材料，硅电子芯片之间的光学通信数据传输速率已达到一个限制，从而阻止了高速智能手机，计算机和互联网设备的持续开发。尽管硅的性能非常适合电子设备，但基于硅的光源无法有效，高速通信。在材料基因组计划的框架内，该项目将寻求新的材料和相关的制造过程来克服这一障碍。最近，已经显示，MDC材料（例如二硫化钼）可以在二氧化硅底物上的大规模，高质量，原子薄膜中生长。 从理论上讲，可以预测，这种材料是具有可调，直接带隙的半导体，它在光学通信应用中比硅更高。该研究项目旨在对理论驱动的对这种原子上薄的材料的制造和控制的理解，以验证其作为芯片光源的使用，以供将来的光学互连用于综合电路。 PI在各自机构内促进STEM活动方面有着很好的记录。他们打算与高中生，本科生和研究生一起工作，并让来自代表性不足的小组的学生参与计划的研究。该项目中提出的宣传活动是扎实的，并且肯定会产生更广泛的社会影响。该项目的目标是在原子材料理论与化学材料合成各种2D金属二分法分子及其合金之间建立连续的知识联系，以发现，合成和综合应用程序的应用程序和促进应用程序的应用程序和促进应用程序的范围和促进应用程序的基础。它建立在首席研究人员的最新发现之上，例如不同金属核苷阶段的应变稳定，连续的单层钼二硫化物膜的MM尺度增长，以及损耗管理以及激光设备的演示光学模式尺寸的尺寸低于光线的差异限制。研究合作者将结合广泛材料的理论筛选和其结构底物稳定的预测建模，以及为多种材料集的增长方法的开发，以及对测试的波导的应用 - 纳入功能评估。该项目汇集了一组跨学科的方法，包括分析和数值模拟，化学过程开发以及芯片集成激光器设备的设计和表征。材料开发方法基于垂直的，基于理论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2D材料领域提供输入，这将在新型光子整合电路和潜在传感器的发展中发挥作用。
