A microspectroscopic insight into the resistivity switching of individual Ag–TCNQ nanocrystals†
We investigate the resistivity switching in individual Ag–TCNQ wires with on/off-ratios of up to 103. Raman and soft X-ray absorption microspectroscopy studies disclose reverse charge transfer. Quantifying of the fraction of neutral TCNQ within the switched material yields values up to 22.3%. These findings expedite the understanding of the switching process in Ag–TCNQ nanowires.
