Electron Correlations in Strongly Disordered Low Dimensional Systems

该个人研究者奖支持一个项目，以解决与低维系统中的电子传输和隧道相关的基础科学问题，这些问题与未来几代微电子技术相关。有两个主要的科学推动力。第一个是使用超冷压缩超薄膜来研究低维、强无序和电子-电子相关如何导致新的行为，如多重磁导、硬相关间隙、电子玻璃和电流驱动的绝缘体到超导体的转变。提出了新型超导场效应器件。二是对各种电化学制备的超薄膜和纳米线进行了表征。当前的目标是开发新的方法，如原位接触法和电子束光刻，使电接触到直径为2-200纳米的单纳米线，并进行传输和隧道测量。该项目为学生提供了一个跨学科的学习环境，包括物理，电化学和纳米制造，这将为他们未来在学术界或工业界的职业生涯做好准备。它还将使罗切斯特大学的一个新的化学物理项目受益。报告概述了一些研究项目，这些项目将为女性和来自科学界代表性不足群体的学生提供外联服务。该个人研究者奖支持解决与低维系统中电子传输和隧道相关的基础科学问题的研究，这些问题与未来几代微电子技术相关。本项目将对超薄膜、电子束光刻制造的介观结构和电化学自组装制造的纳米材料进行实验研究。该研究项目的成果将对低维系统领域的基础科学以及新物理原理、新材料、新器件和新制造技术的发展产生广泛的影响。该项目为学生提供了一个跨学科的学习环境，包括物理，电化学和纳米制造，这将为他们未来在学术界或更广泛的高科技行业的职业生涯做好准备。它还将使罗切斯特大学的一个新的化学物理项目受益。报告概述了一些研究项目，这些项目将为女性和来自科学界代表性不足群体的学生提供外联服务。

This individual investigator award supports a project to address fundamental scientific issues associated with electron transport and tunneling in low-dimensional systems that have technical relevance to future generations of microelectronics. There are two main scientific thrusts. The first is to use quench-condensed ultrathin films to investigate how low dimensionality, strong disorder, and electron-electron correlations can lead to novel behavior such as multifold magnetoconductance, a hard correlation gap, the electron glass, and a current-driven insulator-to-superconductor transition. New superconducting field-effect devices are proposed. The second is to characterize a variety of electrochemically fabricated ultrathin films and nanowires. The immediate goal is to develop novel methods, such as an in-situ contact method and electron-beam lithography, to make electrical contacts to single nanowires, of 2-200 nm in diameter, and to carry out transport and tunneling measurements. The project provides the students with an interdisciplinary learning environment integrating physics, electrochemistry, and nanofabrication, which will prepare them for future careers in either academia or industry. It will also benefit a new chemical physics program at the University of Rochester. Research projects are outlined that will provide outreach to women and students from groups underrepresented in science.This individual investigator award supports research to address fundamental scientific issues associated with electron transport and tunneling in low-dimensional systems that have technical relevance to future generations of microelectronics. This project will carry out experimental studies of ultrathin films, mesoscopic structures fabricated by electron-beam lithography, and nano-sized materials fabricated by electrochemical self-assembly. The results from this research program will have a broad impact on basic science in the field of low-dimensional systems, as well as on the development of new physical principles, new materials, new devices, and new fabrication techniques for future generations of microelectronics.
