Fermi Surface Studies of Organic Superconductors

9402655 Jean这项建议提供资金，以购买正电子源，并对一类有机超导体进行探索性研究。这些材料是双(乙二硫基)四硫富瓦烯配合物，以及新的富勒烯C-60材料。该项目包括确定正电子湮没在该材料中的角分布的实验方法，以及根据这些材料中的费米面对这些数据进行量子化学计算的方法。这些结果具有基本意义，但也可能具有重要的技术意义，因为它们提供了有关这些材料中超导状态的信息。***

9402655 Jean This proposal provides funds to purchase a positron source and pursue exploratory studies of a class of organic superconductor. The materials are bis(ethylenedithio)tetrathiafulvalene complexes, as well as the new fullerene C-60 materials. The project involves both experiment methods to determine the angular distribution of positron annihilation in that materials, and quantum chemical calculations to provide an interpretation of these data in terms of the Fermi surface in these materials. The results are of fundamental interest but may also be of technical importance as they provide information about the superconducting state in these materials. ***
