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.

佛罗里达大学的戴维·坦纳（David Tanner）与匈牙利固态物理和光学研究所的卡塔尔林·卡玛拉斯（Katalin Kamaras 。研究人员打算检查富勒烯和富勒烯衍生物在晶体和薄膜形式中的光学特性。 晶体样品将在布达佩斯和盖恩斯维尔的薄膜样品中制备。 目的是确定通过紫外线频率范围从远红外的富勒底晶体的几个阶段的光功能。 结果预计将提高我们对：1）富勒烯球的对称性，2）它们的电子结构和化学键合，以及3）金属/富勒烯接口处移动荷载流子的动力学特性。 这些新信息应有助于定义一类新的超导材料。本材料研究项目实现了计划的目标，即通过使美国和中欧的专家能够结合互补才能并在具有强大的共同利益和强烈共同兴趣和强烈共同兴趣的领域共享研究资源来促进科学知识的目标。权限。
