摘要: In this work, a high power continuous-wave (CW) Nd:YAG laser was used for thermal treatment of inkjet-printed Ag films - resulting in the elimination organic additives (dispersant, binder, and solvent) ink annealing nano-particles. By optimizing parameters such as defocusing value, energy can be totally converted into heat energy, which is films. This results microstructure resistivity to controlled. We investigated diffusion mechanisms during microstructures. The impact on microstructures electrical characteristics compared those annealed by conventional furnace annealing. Focused ion beam (FIB) channeling images show that have large columnar grains dense void-free structure, while much smaller exhibit void formation. As result, better properties (low resistivity) samples.
