a, b S(2p) XPS results of Fe(DS)3 and PEDOT:DS. The doublet at high binding energies (170 − 166 eV) originates from the sulfate anions and the doublet at low energies (166.5−162.5 eV) corresponds to the thiophene rings of PEDOT. c In-plane XRD of pristine PEDOT and de-doped PEDOT films, (d) out-of-plane GIWAXS diffractogram of PEDOT, and (e) S(2p) multiplex XPS of PEDOT film after de-doping.
