A novel switching property of conducting polymer nanowires is observed. The change in resistance was found to be more than three orders of magnitude (see figure) and the threshold voltage (current) can be tuned by playing with the diameter and/or temperature. The switching mechanism observed in this structurally disordered material is found to be similar to that of charge‐density‐wave systems observed in nanowires of crystalline substances.
