US-France Cooperative Research: Spectroscopy of Carbon Nanotubes in High Magnetic Fields

这个为期三年的美法合作研究项目涉及赖斯大学的河野Junichiro和他的小组，以及法国图卢兹保罗萨巴捷大学国家脉冲实验室的G. L. Rikken领导的研究小组。他们提出在单壁碳纳米管上进行磁吸收、磁发光和电子自旋共振实验。该项目为首席研究员的研究资助增加了一个国际维度，包括他的职业奖，由美国国家科学基金会材料研究部支持。单壁碳纳米管（SWNTs）是一种近一维（1-D）体系，具有广泛的新颖和有用的电子、机械、磁性和光学性质。本项目的目标是探索高磁场下单壁碳纳米管光学和自旋共振特性的新颖一维物理特性。单壁碳纳米管可以提供半导体量子线的替代方案。更广泛的影响提议的联合实验将推进对放置在强磁场中的纳米结构中的电子态的认识，并可能导致新的纳米基材料。它利用了法国独特的设施，特别是独特的75特斯拉脉冲磁铁，可用于各种光学实验。该项目还为研究生和博士后提供了与法国国家科学研究中心的法国研究人员领导小组进行沉浸式研究的国际经验。

0437342KonoThis three-year U.S. France cooperative research project involves Junichiro Kono and his group at Rice University and the research team, led by G. L. Rikken, at the Laboratoire National des Champs Magnetiques Pulses, at the University Paul Sabatier in Toulouse, France. They propose to perform jointly magneto-absorption, magneto-luminescence, and electron spin resonance experiments on single-walled carbon nanotubes. The project adds an international dimension to the principal investigator's research grants, including his CAREER award, supported through NSF's Division of Materials Research.Intellectual Merit Single-walled carbon nanotubes (SWNTs) are a nearly one-dimensional (1-D) system the possesses a wide range of novel and useful electronic, mechanical, magnetic, and optical properties. The goal of this project is to explore novel 1-D physics in the optical and spin resonance properties of SWNTs in high magnetic fields. SWNTs may provide an alternative to semiconductor quantum wires. Broader Impacts The proposed joint experiments will advance knowledge on electronic states in nanostructures placed in intense magnetic fields and could lead to new nano-based materials. It takes advantage of unique facilities in France, in particular, a unique pulsed magnet of 75 Teslas that can be used for various optical experiments. The project also gives graduates students and postdoctoral students an international experience via research immersion with a leading group of French researchers from the French National Center for Scientific Research.
