High Resolution Image Download MS PowerPoint Slide Superconductivity was discovered in (InSe 2 ) x NbSe 2 . The materials are crystallized in a unique layered structure where bonded InSe 2 layers are intercalated into the van der Waals gaps of 2H-phase NbSe 2 . The (InSe 2 ) 0.12 NbSe 2 superconductor exhibits a superconducting transition at 11.6 K and critical current density of 8.2 × 10 5 A/cm 2 . Both values are the highest among all transition metal dichalcogenide superconductors at ambient pressure. The present finding provides an ideal material platform for further investigation of superconducting-related phenomena in transition metal dichalcogenides.
