Low-temperature, solution-processed silver nanowire electrodes for high-performance bottom-contact organic field-effect transistors |
| 초록 |
We successfully fabricate high performance bottom-contact organic field-effect transistors using AgNW networks electrodes by spray deposition. The synthesized AgNWs have the dimension of 40-80 nm in diameter and 30-80 µm in length and are randomly distributed and interconnected to form a 3D hollow framework. The AgNWs networks yield an average optical transmittance of up to 88 % and a sheet resistance as low as 10 ohm/sq. To enhance charge injection, we fabricate semiconductor crystals on the AgNW using adsorbed residual poly(N-vinylpyrrolidone) layer. The resulting bottom-contact OFETs exhibit high mobility up to 1.02 cm2/Vs, and are similar to that of the top-contact Au electrodes OFETs with low contact resistance. The pentacene crystals coalesced to form continuous morphology on the nanowires, and are highly interconnected with those on the channel. These features contribute to efficient charge injection and encourage the improvement of the bottom-contact device performance. |
