2D Crystal Semiconductors: Electron Transport and Device Applications

该计划的目标是解开科学，并实现2D晶体半导体的技术潜力，专注于未来几代电子设备。智力上的优点是在一系列新的原子薄二维晶体的控制晶体生长科学的发展和对其物理性质的理解。二维晶体半导体的电子输运性质目前还没有得到很好的理解。然而，再加上静电，它是设备应用的关键。因此，本项目旨在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输运性质。它们在大面积、轻便、灵活和透明的高性能电子开关中的应用将是一项变革性的技术。更广泛的影响是通过一个外联计划，有效地利用新兴领域的兴奋和非凡的承诺，新来者可以做出重大和持久的贡献。拟议的项目涉及几个学生。以理论为导向的学生将在模拟能带图和器件结构的层面参与项目。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。他们将直接与博士后学者和pi合作，参加会议并介绍他们的工作。该项目将培养研究生解决一个令人着迷的问题及其对电子和光学器件的许多基本影响。除了扩大pi正在策划的现有外联方案外，还提议开展两项新活动，特别关注代表性不足的群体：1)在“拓展你的视野”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这里，早期接触到科学和技术是如何在各种职业中应用的；2)为圣玛丽大学(St. Mary？年代上大学。通过出版物和会议报告传播研究成果，并将其纳入研究人员讲授的课程，将确保所提议的研究向尽可能广泛的受众推广。

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.
