Individual single-crystal nanowires as electrodes for organic single-crystal nanodevices

Abstract

Conductive, transparent, and flexible SnO₂:Sb single-crystal nanowires are shown as electrodes for F₁₆CuPc single-crystal nanowire devices on flexible plastic, which includes anisotropic-transport OFETs, electrode-movable OFETs, and p–n junction photovoltaic devices. The SnO₂:Sb nanowires provide a good energy level match and excellent soft contact with F₁₆CuPc nanowires, leading to multifaceted applications of the SnO₂:Sb nanowire in nanowire electronics and optoelectronics, as well as high device performance. Combined with their good size compatibility, these results show that the conductive SnO₂:Sb single-crystal nanowire opens a window into the fundamental understanding of the intrinsic properties of highly ordered organic semiconductors, optimization and miniaturization of organic nanocircuits, and development of new-generation flexible organic nanodevices.
