In Situ Determination of Thermodynamic, Magnetic, and Transport Properties of Doped and Undoped Thin Film C60

通过研究掺杂C60薄膜的热力学、磁性、输运和超导隧穿特性，在包括超导和取向结构转变在内的广泛温度范围内原位测量，将探索掺杂C60薄膜的超导电性和金属行为。关于超导耦合的性质、球内和球间相互作用、费米表面的电子态密度、特征声子频率、电子-声子相互作用以及球间传导的形成等基本问题，将通过一系列测量来解决，包括比热、磁化率、电阻率和霍尔效应。超导隧道谱将被用来表征超导相互作用的强度和频率依赖性。薄膜沉积技术将使亚稳定相的探索成为可能。

Superconductivity and metallic behavior in thin films of doped C60 will be probed by studying their thermodynamic, magnetic, transport and superconductive tunneling properties, measured in situ over a wide range of temperature encompassing both the superconducting and orientational structural transitions. Fundamental questions concerning the nature of the superconducting coupling, inter- and intra-ball interactions, electron density of states at the Fermi surface, characteristic phonon frequencies, electron-phonon interaction, and the formation of the interball conduction will be addressed through a series of measurements including specific heat, magnetic susceptibility, resistivity, and Hall effect. Superconductive tunneling spectroscopy will be used to characterize the strength and frequency dependance of the superconducting interaction. Thin film deposition techniques will permit the exploration of metastable phases.
