摘要

最近报道了K掺杂的1,2:8,9-二苯并戊二烯(C30H18)的高温超导性[1]，Tc = 33 K，在环境压力下是有机超导体中最高的。在这里，我们报告了我们对K, Ba和ca掺杂碳氢化合物有机材料的超导性的研究。我们发现ba -蒽(C14H10)和k -蒎烯(C22H14)虽然非常弱，但表现出超导态的特征。结果表明，ba -蒽可能是一种Tc ~ 35k的新型有机超导体。

On the nature of filamentary superconductivity in metal-doped hydrocarbon organic materials

Abstract High temperature superconductivity in K-doped 1,2:8,9-dibenzenopentacene (C30H18) has been recently reported [1] with Tc = 33 K, the highest among organic superconductors at ambient pressure. Here we report on our search for superconductivity in K, Ba, and Ca-doped hydrocarbon organic materials. We find that Ba-anthracene (C14H10) and K-Picene (C22H14) show features characteristics of superconducting state, although very weak. The data suggests that Ba-anthracene might be a new organic superconductor with Tc ~35 K.
