From: Metal to insulator transition for conducting polymers in plasmonic nanogaps
a Dynamic response in DF scattering of Au@PEDOT NPoMs with 2, 4, 9, 14 nm PEDOT shells in 0.5 M NaCl electrolyte. Scan rate: 50 mV s−1. b Corresponding DF scattering spectra of single NPoMs of each thickness. P0, PEDOT0; P2+, PEDOT2+. c Optical tuning and d corresponding intensity switching of NPoMs vs PEDOT thickness (gap size). e Tuning hysteresis and effect of different anions on DF scattering of NPoMs vs applied potential. Scan rate: 50 mV s−1. f Effect of scan rate on dynamic response in DF scattering of 4, 14 nm gap PEDOT NPoMs vs applied potential in 0.5 M NaNO3 electrolyte
