Caging-Pnictogen-Induced Superconductivity in Skutterudites IrX3 (X = As, P)

Cuiying Pei, Tianping Ying, Qinghua Zhang +12

Here we report on a new kind of compound, XδIr4X12-δ (X = P, As), the first hole-doped skutterudites superconductor. We provide atomic resolution images of the caging As atoms usin…
