Superconductivity in Cu-Intercalated CdI2-Type PdTe2

We found a new Cu-intercalated bulk superconductor of CdI2-type Cu0.05PdTe2 with a large shielding volume fraction of almost 100 %. In particular, in this layered superconductor, Cu atoms are intercalated between the van der Waals layers. A large Cu-intercalated PdTe2 single crystal is also successfully grown using the conventional self-flux method using the quartz tube with the narrow cone-type seed zone of 1 cm. This result indicates that Cu x PdTe2 is a new example of intercalation-based layered superconductor.
