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. An educational extension of the research effort 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.

技术：加州大学河滨分校 (UCR) 该学院早期职业发展的目标是通过实验研究与普通电极和超导电极耦合的石墨烯器件中电荷的量子传输。石墨烯是单层碳原子，自 2004 年实验分离以来引起了极大的关注。石墨烯中的电子行为类似于相对论、无质量的狄拉克费米子，预计会表现出诸如韦塞拉戈透镜（类似光学的电荷聚焦）等新颖现象）。其材料特性，例如高导电性和导热性，使其成为后硅器件工程非常理想的电子材料。该项目将提供有关石墨烯基本电特性的重要信息，并在基于石墨烯的电子设备中实现新功能。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，预计这将产生热电和自旋的无电荷传输等新现象。研究工作的教育延伸是开发实验室课程“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兴奋。利用加州大学河滨分校学生群体和当地社区的种族多样性，该项目将积极让高中生、本科生和研究生，特别是少数族裔和女性参与前沿研究。非技术性：加州大学河滨分校 (UCR) 该学院早期职业发展的目标是通过实验研究石墨烯与普通电极和超导电极耦合的电特性。石墨烯于 2004 年首次通过实验分离出来，由只有一个原子层厚的碳原子组成，其独特的特性是其电子的行为就好像它们的质量为零一样。石墨烯的这种令人着迷的属性预计会产生许多新奇的现象，例如维塞拉戈透镜（类似光学的电子射线聚焦），这可能会催生新型设备。结合其非常理想的材料特性，例如高导电性和导热性，石墨烯作为后硅电子材料引起了极大的兴趣。该项目将提供有关石墨烯基本电特性的重要信息，并在基于石墨烯的电子设备中实现新功能。研究工作的教育延伸是开发实验室课程（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兴奋。利用加州大学河滨分校学生群体和当地社区的种族多样性，该项目将积极让高中生、本科生和研究生，特别是少数族裔和女性参与前沿研究。
