U.S.-Hungary Materials Research on the Optical Properties of Fullerenes

这个由佛罗里达大学的David Tanner和匈牙利固体物理与光学研究所的Katalin Kamaras合作的美国-匈牙利研究项目的特点是样品制备和使用微光谱学在惰性气体气氛中对空气敏感材料进行原位研究。研究人员打算研究富勒烯和富勒烯衍生物在晶体和薄膜形式下的光学性质。晶体样品将在布达佩斯制备，薄膜样品将在盖恩斯维尔制备。目的是确定从远红外到紫外频率范围内富勒化物晶体的几个相的光学功能。研究结果有望提高我们对以下方面的理解：1)富勒烯球的对称性，2)它们的电子结构和化学键，以及3)金属/富勒烯界面上移动电荷载流子的动力学性质。这一新信息将有助于定义一类新的超导材料。该材料研究项目通过使美国和中欧的专家能够在共同感兴趣和能力强的领域结合互补的人才和共享研究资源，实现了推进科学知识的计划目标。

INT 9902050TannerThis U.S.-Hungary research project between David Tanner of the University of Florida and Katalin Kamaras of the Hungarian Institute for Solid State Physics and Optics features sample preparation and use of microspectroscopy for in-situ study of air-sensitive materials in an inert gas atmosphere. The researchers intend to examine the optical properties of fullerenes and fullerene derivatives in crystal and thin film forms. Crystalline samples will be prepared in Budapest and the thin film samples in Gainesville. The intent is to determine the optical functions of several phases of fulleride crystals from the far infrared through ultraviolet frequency ranges. Results are expected to improve our understanding of: 1) the symmetry of fullerene balls, 2) their electronic structure and chemical bonding, and 3) the dynamical properties of mobile charge carriers at metal/fullerene interfaces. This new information should help define a new class of superconducting materials.This materials research project fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.
