Single-crystal organic nanowires of copper-tetracyanoquino-dimethane: Synthesis, patterning, characterization, and device applications

(Figure Presented) Current events: Nanowires of the organic semiconductor copper-tetracyanoquino-dimethane (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.
