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.

基于原子级薄的二维（2D）材料（例如层状过渡金属二硫属化物（TMDC））建立电子技术的基础可能在依赖于柔性电子和纳米电子系统的许多技术领域中被证明是变革性的。该项目将为未来的2D TMDC电子技术建立一个关键的知识库，用于广泛的应用，如低功耗计算，柔性显示器和可穿戴电子产品。该项目通过参与大学和工业合作伙伴之间的各自合作和技术转让产生直接的工业影响。它还将提供跨学科的研究机会，为培养研究生，以及本科生和高中生，在大学和工业界之间的合作研究环境，并通过传播基于网络的学习模块，模拟器，和TDMC的实验数据-虽然TMDC材料由于其机械可弯曲性而有希望用于纳米电子学和柔性电子学中的许多潜在应用，原子级薄的厚度和优异的本征载流子输运性质，在将这些材料的早期科学转化为实际电路和系统技术方面存在主要差距。本项目的目标是为基于二维TMDC的新型器件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.沃森研究中心作为工业合作伙伴。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TMDC晶体管的紧凑电路模型相集成，（ii）制造，表征和仿真基本TMDC电路，（iii）建模TMDC晶体管中的可变性和缺陷机制及其相关性，以及（iv）设计和实验演示透明柔性显示器的TMDC驱动电路。
