Abstract:
We investigate the resistivity switching in individual Ag-TCNQ wires with on/off-ratios of up to 10(3). 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.
