The objective of this program is to unravel the science, and realize the technological potential of 2D crystal semiconductors focused on future generations of electronic devices. The intellectual merit is in the development of the science of controlled crystal growth of a range of new atomically thin 2D crystals and in the understanding of their physical properties. The electronic transport properties in 2D crystal semiconductors are currently not well understood. Yet, coupled with electrostatics, it is the key to device applications. Thus, this project aims directly at developing a thorough understanding of the transport properties of electrons in 2D crystal semiconductors through a combined experimental and modeling approach. The demonstration of their usage in large area, light, flexible and transparent high-performance electronic switches will be a transformative technology.The broader impacts are through an outreach program that effectively exploits the excitement and exceptional promise of the fledgling field, one where newcomers can make significant and lasting contributions. The proposed project involves several students. The theoretically oriented students will be involved in the project at the level of simulations of energy band diagrams and device structures. The experimentally inclined students will be involved in measurements of 2D crystal semiconductor properties and analysis. They will work directly with the PostDoctoral scholars, and the PIs by attending meetings and presenting their work. The project will result in the training of graduate students in a fascinating problem and its many fundamental consequences for electronic and optical devices. In additional to expanding the existing outreach programs that the PIs are orchestrating, two new activities are proposed with a special focus on the underrepresented groups: 1) experimental demonstration of nanoscale scanning probe techniques at the Expanding Your Horizon workshops where young school girls gather for their early exposure to how science and technology are employed in various careers, and 2) research projects designed for the women undergraduate students under the Dual Degree Program at the St. Mary?s College. The dissemination of research results by publications and presentations at conferences, and its inclusion in courses taught by the investigators will ensure the outreach of the research proposed to the widest possible audience.

该计划的目标是阐明科学，并实现专注于未来几代电子设备的二维晶体半导体的技术潜力。 其智力价值在于一系列新型原子薄二维晶体的受控晶体生长科学的发展以及对其物理性质的理解。 目前，二维晶体半导体的电子输运特性尚不清楚。 然而，与静电相结合，它是设备应用的关键。 因此，该项目的直接目的是通过实验和建模相结合的方法，全面了解二维晶体半导体中电子的传输特性。展示它们在大面积、轻型、灵活和透明的高性能电子开关中的应用将是一项变革性技术。更广泛的影响是通过一项推广计划来实现的，该计划有效地利用了这个新兴领域的兴奋点和非凡的前景，新来者可以在其中做出重大而持久的贡献。 拟议的项目涉及几名学生。 理论导向的学生将参与能带图和器件结构模拟级别的项目。 有实验倾向的学生将参与二维晶体半导体特性的测量和分析。 他们将通过参加会议并展示他们的工作来直接与博士后学者和 PI 合作。 该项目将培训研究生解决一个令人着迷的问题及其对电子和光学设备的许多基本影响。 除了扩大 PI 正在策划的现有外展计划外，还提出了两项​​新活动，特别关注代表性不足的群体：1）在“扩展你的视野”研讨会上进行纳米级扫描探针技术的实验演示，年轻的女学生聚集在研讨会上进行纳米级扫描探针技术的实验演示。尽早接触科学技术如何应用​​于各种职业，以及 2) 在圣玛丽学院双学位项目下为女本科生设计的研究项目。 通过出版物和会议上的演讲传播研究成果，并将其纳入研究人员教授的课程中，将确保将拟议的研究推广到尽可能广泛的受众。
