Description:
Author(s): R. J. Sun, Y. Quan, S. F. Jin, Q. Z. Huang, H. Wu, L. Zhao, L. Gu, Z. P. Yin, and X. L. Chen Iron selenide superconductors exhibit unique characteristics distinct from iron pnictides, especially in the electron-doped region. Here, the authors report the synthesis of a new family of Li x (C 3 N 2 H 10 ) 0 . 37 FeSe materials, which features a continuous superconducting dome harboring a Lifshitz transition within the wide range of 0.06 ≤ x ≤ 0.68. Under electron doping, the anion height of FeSe layers deviates linearly away from the optimized values of pnictides. This feature leads to a new superconducting zone with unique electronic structures and strong orbital-selective electronic correlation. [Phys. Rev. B 98, 214508] Published Wed Dec 12, 2018
