摘要：
We report specific-heat studies on high-quality Ba-doped phenanthrene, one of the organic superconductors with fused benzene rings, with 100% shielding fraction. The specific-heat data indicate that Ba-doped phenanthrene is a single-gap s-wave superconductor with moderate coupling, and this sets constraints on theoretical models for the understanding of superconductivity in these hydrocarbon superconductors.
