• 論文の詳細を見る

• We investigated the field-effect characteristics of mechanically stretched regio-regular poly(3-hexylthiophene) (P3HT) on a supporting poly(vinyl alcohol) (PVA) film. After stretching the P3HT/PVA film, large dichroism was observed in the polarized UV-Vis absorption spectra. The stretched P3HT films were applied parallel or orthogonal to the conduction channel of the transistor. The field-effect mobility was highly anisotropic, with larger mobility along the stretched direction of the films. The mobility increased with increasing stretch ratio (Sr) for the parallel devices but decreased for the orthogonal devices.
