0437342 Kono这个为期三年的美法合作研究项目涉及莱斯大学的河野纯一郎和他的团队，以及法国图卢兹保罗·萨巴蒂埃大学国家香榭丽舍磁脉冲实验室的G.L.Rikken领导的研究团队。他们建议在单壁碳纳米管上联合进行磁吸收、磁致发光和电子自旋共振实验。该项目为首席研究人员的研究拨款增加了国际维度，包括由NSF材料研究部支持的职业奖励。智能优点单壁碳纳米管(SWNTs)是一种近一维(1-D)的系统，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单壁碳纳米管在强磁场中的光学和自旋共振性质的新的一维物理。单壁碳纳米管有可能成为半导体量子线的替代材料。更广泛的影响拟议的联合实验将促进对置于强磁场中的纳米结构中电子状态的了解，并可能导致新的纳米材料。它利用了法国独特的设施，特别是一种独特的75特斯拉的脉冲磁铁，可以用于各种光学实验。该项目还通过与来自法国国家科学研究中心的法国研究人员领导小组的研究沉浸在一起，为研究生和博士后提供国际体验。

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.
