37. Next issue to conclude this is to fabricate Ag nanoparticles with various morphologies, i.e. sizes, shapes and roughness, in addition to adopt various adsorbates with distinct molecular vibration or electronic states. Preliminary, we confirmed that the citrate method with much shorter incubation (annealing) time at 100°C, e.g. 5-10 min, compared to standard time of 45 min did not change the inelastic peak position
38. Local electric field at the gap was evaluated with a homogeneous grid of 2 nm. More precise and quantitative analysis are being progressed with finer meshes at the gap region, although essential features were already obtained here
