Establishing the foundation for electronics technology based on atomically thin two-dimensional (2D) materials, such as layered transition metal dichalcogenides (TMDCs), may prove to be transformative in many technological areas relying on flexible electronic and nanoelectronic systems. This project will establish a critical knowledge base for future 2D TMDC electronics technology for a broad range of applications, such as low power computing, flexible display, and wearable electronics. The project has a direct industrial impact through the respective collaboration and technology transfer between the participating universities and the industrial partner. It will also offer interdisciplinary research opportunities for training graduate students, as well as undergraduate and high school students, in a collaborative research environment between university and industry, and provide valuable resources for research and educational community by disseminating web-based learning modules, simulators, and experimental data on TDMC-based electronics.While TMDC materials are promising for many potential applications in nanoelectronics and flexible electronics due to their mechanical bendability, atomically thin thickness, and excellent intrinsic carrier transport properties, major gaps exist on translating early science of such materials into practical circuit and system technologies. The objective of this project is to develop compact model and circuit-simulation platform for new 2D TMDC-based devices and systems, and to explore its applications in flexible and wearable electronic systems through experimental demonstration and collaboration with IBM T. J. Watson Research Center as the industrial partner. The proposal will undertake the following tasks: (i) develop a multiscale simulation framework that integrates atomistic device simulations with compact circuit models for TMDC transistors, (ii) fabricate, characterize and simulate basic TMDC circuits, (iii) model the variability and defect mechanisms and their correlations in TMDC transistors, and (iv) design and experimentally demonstrate TMDC driving circuits for transparent flexible display.

建立基于原子薄二维（2D）材料的电子技术基础，如层状过渡金属二硫族化合物（TMDCs），可能会在依赖柔性电子和纳米电子系统的许多技术领域产生变革。该项目将为未来2D TMDC电子技术的广泛应用建立关键知识库，如低功耗计算、柔性显示和可穿戴电子产品。该项目通过参与大学和工业伙伴之间的各自合作和技术转让，对工业产生直接影响。它还将在大学和工业之间的合作研究环境中为培养研究生、本科生和高中生提供跨学科研究机会，并通过传播基于tdmc的电子产品的基于网络的学习模块、模拟器和实验数据，为研究和教育界提供宝贵的资源。虽然TMDC材料由于其机械可弯曲性、原子薄厚度和优异的固有载流子输运特性而在纳米电子学和柔性电子学中具有许多潜在的应用前景，但在将此类材料的早期科学转化为实际的电路和系统技术方面存在主要差距。该项目的目标是为新的基于二维tmdc的设备和系统开发紧凑的模型和电路仿真平台，并通过实验演示和与IBM T. J. Watson研究中心作为工业合作伙伴的合作，探索其在柔性和可穿戴电子系统中的应用。该提案将承担以下任务：(i)开发一个多尺度仿真框架，将原子器件仿真与紧凑的TMDC晶体管电路模型集成在一起；（ii）制作、表征和模拟基本的TMDC电路；（iii）模拟TMDC晶体管中的可变性和缺陷机制及其相关性；（iv）设计和实验演示透明柔性显示的TMDC驱动电路。
