DESCRIPTION:Distinctive superconducting behaviors between bulk and monolaye
 r FeSe make it challenging to obtain a unified picture of all FeSe-based s
 uperconductors. Here\, we investigate the ultrafast quasiparticle dynamics
  of an intercalated superconductor (Li<sub>1-x</sub>Fe<sub>x</sub>)OHFe<su
 b>1-y</sub>Se\, which is a bulk crystal but shares a similar electronic st
 ructure with single-layer FeSe on SrTiO<sub>3</sub>. We obtain the electro
 nphonon coupling (EPC) constant λ (0.24 ± 0.03)\, which well bridges tha
 t of bulk FeSe crystal and single-layer FeSe/SrTiO3 [1]. Moreover\, we fin
 d that such a positive correlation between λ and superconducting T<sub>c<
 /sub> holds among all knownFeSe-based superconductors\, even in line with 
 reported FeAs-based superconductors. Our observation indicates possible un
 iversal role of EPC in the superconductivity of all known categories of ir
 on-based superconductors\, which is a critical step towards achieving a un
 ified superconducting mechanism for all iron-based superconductors.Referen
