CAREER: Quantum Transport of Charges in Graphene

技术：加州大学河滨分校（UCR）教师早期职业发展的目标是通过实验研究石墨烯器件中与正常和超导电极耦合的电荷的量子输运。石墨烯是一种单层碳原子，自2004年实验分离以来引起了极大的关注。石墨烯中的电子表现得像相对论性的、无质量的狄拉克费米子，并且预计会表现出新的现象，比如维塞拉格透镜（类似光学的电荷聚焦）。它的材料特性，如高导电性和导热性，使其成为后硅器件工程中非常理想的电子材料。该项目将提供关于石墨烯基本电学特性的重要信息，并为石墨烯基电子设备提供新功能。此外，该项目探索了超导性和相对论性粒子之间的相互作用，这有望产生新的现象，如热电和自旋的无电荷输运。研究工作的教育延伸是开发一门实验课程，纳米结构的制造和表征，旨在为本科物理教育带来现代工具和乐趣。利用UCR学生人口和当地社区的种族多样性，该项目将积极吸引高中生，本科生和研究生，特别是少数民族和女性，参与前沿研究。非技术：加州大学河滨分校（UCR）教师早期职业发展的目标是实验研究石墨烯与正常和超导电极耦合的电学特性。石墨烯于2004年首次通过实验分离出来，它由只有一个原子层厚度的碳原子组成，其独特的特性是其电子的行为就像它们的质量为零一样。据预测，石墨烯的这一迷人特性将产生许多新现象，如维塞拉格透镜（电子射线的光学聚焦），这可能会使新型设备成为可能。石墨烯具有优异的材料性能，如高导电性和导热性，作为后硅电子材料引起了极大的兴趣。该项目将提供关于石墨烯基本电学特性的重要信息，并为石墨烯基电子设备提供新功能。研究工作的教育延伸是开发一门实验课程（纳米结构的制造和表征），旨在为本科物理教育带来现代工具和乐趣。利用UCR学生人口和当地社区的种族多样性，该项目将积极吸引高中生，本科生和研究生，特别是少数民族和女性，参与前沿研究。

Technical:The goal of this Faculty Early Career Development at University of California, Riverside (UCR) is to experimentally investigate quantum transport of charges in graphene devices coupled to normal and superconducting electrodes. Graphene is a single layer of carbon atoms, and has attracted tremendous attention since its experimental isolation in 2004. Electrons in graphene behave like relativistic, massless Dirac fermions, and are predicted to exhibit novel phenomena such as Veselago lensing (optics-like focusing of charges). Its materials properties, such as high electrical and thermal conductivity, have made it a highly desirable electronic material for post-silicon device engineering. This project will provide important information on the fundamental electrical properties of graphene, and enable new functionalities in graphene-based electronic devices. In addition, this project explores the interplay between superconductivity and relativistic particles, which is expected to give rise to novel phenomena such as chargeless transport of thermopower and spin. An educational extension of the research efforts is the development of a laboratory course, Fabrication and Characterization of Nanostructures, that aims at bringing modern tools and excitement to undergraduate physics education. Taking advantage of the ethnic diversity of UCR's student population and local communities, this project will actively involve high school, undergraduate, and graduate students, especially minority and women, in cutting-edge research. Non-technical: The goal of this Faculty Early Career Development at University of California, Riverside (UCR) is to experimentally investigate the electrical properties of graphene coupled to normal and superconducting electrodes. Graphene, first experimentally isolated in 2004, consists of carbon atoms only one atomic layer thick, with the unique characteristic that its electrons behave as if they have zero mass. This fascinating attribute of graphene is predicted to give rise to many novel phenomena, such as Veselago lensing (optics-like focusing of electron rays), that may enable new types of devices. Combined with its highly desirable materials properties, such as high electrical and thermal conductivity, graphene has attracted tremendous interest as a post-silicon electronic material. This project will provide important information on the fundamental electrical properties of graphene, and enable new functionalities in graphene-based electronic devices.
