dc.description.abstract | An inkjet-printed silver electrode and a spin-coated cross-linked poly(4-vinylphenol)(PVP)
dielectric layer were used as a gate electrode and a gate insulator for a bottom-gate pentacene thin- lm transistor (TFT), respectively. The printing and the curing conditions of the printed silver electrode were optimized and tested on various substrates, such as glass, silicon, silicon dioxide, polyethersulfone, polyethyleneterephthalate, polyimide and polyarylate, to produce a good sheet resistance of 0.2 0.4 / and a good surface roughness of 2.38 nm in RMS value and 20.14 nm in peak-to-valley (P2V) value, which are very similar to those of conventionally-sputtered indium-tin- oxide (ITO) or thermally-evaporated silver electrodes. The coated PVP layer of metal/PVP/metal devices showed a good insulation property of 10.4 nA/cm2 at 0.5 MV/cm. The PVP layer further reduced the surface roughness of the gate electrode to provide a good interface to the pentance layer. The pentacene TFT with a structure of glass/printed silver/PVP/pentacene/Au showed a good saturation region mobility of 0.13 cm2/Vs and a good on/o ratio of larger than 105, which are similar to the performance of a pentacene TFT with a conventional ITO gate electrode. | en |
