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.

该程序的目的是阐明科学，并实现针对后代电子设备的2D晶体半导体的技术潜力。 智力优点在于发展一系列新的原子薄晶体的受控晶体生长科学以及对其物理特性的理解。 目前尚不清楚2D晶体半导体中的电子传输性能。 然而，再加上静电，它是设备应用的关键。 因此，该项目直接旨在通过结合的实验和建模方法对2D晶体半导体中电子的传输特性进行彻底了解。它们在大面积，光线，灵活和透明的高性能电子开关中使用的证明将是一种变革性的技术。更广泛的影响是通过一项外展计划，有效利用了刚起步的领域的兴奋和非凡希望，新手可以做出重大和持久的贡献。 拟议的项目涉及几个学生。 理论上的学生将以能量带图和设备结构的模拟级别参与该项目。 实验倾斜的学生将参与2D晶体半导体特性和分析的测量。 他们将直接与博士后学者合作，并通过参加会议并介绍他们的工作。 该项目将导致研究生培训一个令人着迷的问题及其对电子和光学设备的许多基本后果。 除了扩大PI正在策划的现有外展计划外，还提出了两项​​新的活动，特别关注代表性不足的群体：1）在不断扩大的年轻学校的纳米级扫描探测技术的实验证明中，年轻的学校女孩聚集在各种妇女中，他们在研究中雇用了妇女，并在研究中雇用了妇女，以及2）妇女的研究，以及2）玛丽的研究人员？ 大学。 会议上出版物和演讲对研究结果的传播及其包含在调查人员教授的课程中，将确保向最广泛的受众提出的研究的宣传。
