摘要: We have established a well-defined dome shape Tc curve in Ir0.94-xRhxSe2 superconductors. The maximum Tconset of 9.6K was obtained at x=0.36, which the Se-Se separation dimer anion is longest. Simultaneously, destabilization dimers accompanied by partial elec-tron-transfer from Ir/Rh to chalcogenide ions result-ed emergence optimal Tc.
