ChemInform Abstract: Modulation Effect of Interlayer Spacing on the Superconductivity of Electron-Doped FeSe-Based Intercalates

Na/DA and Sr/DA intercalates of FeSe (DA: (H2N)CnH2n(NH2) with n = 0, 2, 3, or 6 as electron sources and molecular spacers) are prepared by a low-temperature ammonothermal method using Na, Sr, FeSe, and condensed NH3 (high-pressure glass vessel, 273-298 K, 2-3 h) followed by the removal of intercalated NH3 (evacuation at 303-373 K).
