Within this joint research project we will prepare various carbon nanostructures and study their electronic and vibrational properties by optical spectroscopy at ambient and high pressure. Our investigations will include füllende salts A4C60 (A=K, Rb, Cs), which are Mott-Jahn-Teller insulators at ambient conditions, several rotor-stator phases consisting of cubane C8H8 and C60, C70 and higher fullerenes, as well as samples of unaligned and aligned single-wall carbon nanotubes, and peapods, i.e., carbon nanotubes filled with fullerenes and fullerene derivatives. The main goal of this joint project is the characterization of phenomena induced by the application of external pressure - like structural phase transitions, insulator-to-metal transition, and polymerization reactions - by means of optical spectroscopy in the far-infrared up to the visible frequency range as a function of pressure. The preparation, characterization, and optical measurements on the carbon nanostructures as a function of temperature and pressure will be carried out partly in Budapest and partly in Augsburg, in close collaboration of the two research groups.

在这个联合研究项目中，我们将制备各种碳纳米结构，并通过常压和高压下的光谱研究它们的电子和振动特性，我们的研究将包括富伦德盐 A4C60（A=K、Rb、Cs），它们是 Mott-Jahn-。环境条件下的柜员绝缘子、由立方烷 C8H8 和 C60、C70 和更高富勒烯组成的多个转子-定子相，以及未排列的样品排列的单壁碳纳米管和豆荚，即填充有富勒烯和富勒烯衍生物的碳纳米管。该联合项目的主要目标是表征由施加外部压力引起的现象，例如结构相变、绝缘体到相变。 -金属转变和聚合反应 - 通过远红外至可见频率范围内的光谱作为压力的函数对碳进行制备、表征和光学测量。纳米结构作为温度和压力函数的研究将部分在布达佩斯进行，部分在奥格斯堡进行，两个研究小组密切合作。
