Abstract

A new ion-transfer-based mechanism is proposed for the growth of CuTCNQ nanowires within the confines of an anodic aluminum oxide template. Remarkably, Cu ions are found to move across the growing solid single-crystalline nanowire at a very high rate with macroscopic distance, as schematically illustrated in the figure.
