2D Crystal Semiconductors: Electron Transport and Device Applications

该计划的目标是揭示科学，并实现专注于未来几代电子设备的2D晶体半导体的技术潜力。 其智力价值在于发展了一系列新的原子级薄2D晶体的受控晶体生长科学，并了解了它们的物理特性。 二维晶体半导体中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，该项目的目标直接是通过实验和建模相结合的方法，深入了解电子在二维晶体半导体中的传输特性。将其应用于大面积、轻便、灵活和透明的高性能电子开关的演示将是一项变革性技术。更广泛的影响是通过有效利用新兴领域的兴奋和特殊前景的推广计划，新来者可以做出重大而持久的贡献。 这个项目涉及几个学生。 理论导向的学生将在能带图和器件结构的模拟水平上参与该项目。 实验倾向的学生将参与2D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一起工作，参加会议并介绍他们的工作。 该项目将导致研究生在一个迷人的问题和它的电子和光学设备的许多基本后果的培训。 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“拓展视野”研讨会上演示纳米级扫描探针技术，年轻的女学生聚集在一起，让她们尽早接触科学和技术如何在各种职业中应用，（2）在圣玛丽双学位课程下为女本科生设计的研究项目。s学院。 通过出版物和在会议上介绍来传播研究成果，并将其纳入研究人员讲授的课程，将确保向尽可能广泛的受众推广拟议的研究。

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.
