摘要: Organic thin-film transistors with a minimal threshold voltage shift and a more stable photocurrent under illuminated conditions can be made by embedding titanium dioxide (TiO2) nanoparticles into a polymer dielectric layer. While the studies of pentacene morphology using atomic force microscopy and X-ray diffraction have shown similar results before and after embedding the TiO2 into the dielectric layer, it has been found that the presence of TiO2 nanoparticles is essential. The reduced photosensitivity can be attributed to the recombination centers induced by the TiO2 nanopartilces and this can enhance substantially the recombination process of the electrons trapped in the channel.
