摘要
We report protonation in several compounds by an ionic-liquid-gating method, under optimized gating conditions. This leads to single superconducting phases for several compounds. Non-volatility of protons allows post-gating magnetization and transport measurements. The superconducting transition temperature T c is enhanced to 43.5 K for FeSe 0.93 S 0.07 , and 41 K for FeSe after protonation. Superconducting transitions with T c ∼ 15 K for ZrNCl, ∼7.2 K for 1T-TaS 2 , and ∼3.8 K for Bi 2 Se 3 are induced after protonation. Electric transport in protonated FeSe 0.93 S 0.07 confirms high-temperature superconductivity. Our 1 H nuclear magnetic resonance (NMR) measurements on protonated FeSe 1− x S x reveal enhanced spin-lattice relaxation rate 1/ 1 T 1 with increasing x, which is consistent with the LDA calculations that H + is located in the interstitial sites close to the anions.
