Abstract

We report on the growth of rubrene ($C_{42}H_{28}$) wire fabricated by thermal evaporation, followed by solvent-vapor annealing for the application of organic thin film transistor. Solvent-vapor annealing was carried out in precisely controlled vapor pressure at elevated temperature. Micro-sized, and elongated rubrene wire was obtained via solvent annealing process reproducibly. Optical image and XRD data shows highly crystalline quality of rubrene wire.
