Superconductivity was discovered in (InSe2)xNbSe2. The materials are crystallized a unique layered structure where bonded InSe2 layers intercalated into the van der Waals gaps of 2H-phase NbSe2. (InSe2)0.12NbSe2 superconductor exhibits superconducting transition at 11.6 K and critical current density 8.2 × 105 A/cm2. Both values highest among all metal dichalcogenide superconductors ambient pressure. present finding provides an ideal material platform for further investigation superconducting-related phenomena dichalcogenides.
