CaGe(3) has been synthesized at high-pressure, high-temperature conditions. The atomic pattern comprises intricate germanium layers of condensed moleculelike dimers. Below T(c) = 6.8 K, type II superconductivity with moderately strong electron-phonon coupling is observed.
CaGe(3) 在高温高压条件下被合成。原子图案由凝聚的类似分子二聚体的复杂锗层组成。在 T(c) = 6.8 K 以下,观察到具有中等强电子-声子耦合的 II 型超导性。
