Single‐Crystal Organic Nanowires of Copper–Tetracyanoquinodimethane: Synthesis, Patterning, Characterization, and Device Applications

Current events: Nanowires of the organic semiconductor copper–tetracyanoquinodimethane (Cu–TCNQ) have been synthesized in a controlled manner and patterned on a variety of substrates by chemical vapor deposition. A cross-point memory device based on a network of Cu–TCNQ nanowires (see picture) has been constructed that repeatedly switches electrically between two states with a conductivity difference of more than two orders of magnitude.
