Extended Data Figure 7

a, Proposed origin of H+ and O2− ions during ILG: the water inside the ionic liquid is decomposed into negatively charged O2− and positively charged H+ ions through electrolysis. b, Gating current (IG) as a function of gating voltage (VG). c, Comparison of SIMS spectra around m/z ≈ 2.0 for samples gated with the as-received ionic liquid DEME-TFSI containing water (H2O), or the developed ionic liquids EMIM-BF4 and DEME-TFSI containing heavy water (D2O). d, Depth profiles of the D+ ions in films gated with the developed ionic liquids containing heavy water.
