Ag dendrites fabrication. Schematic representation of the Ag dendrite fabrication protocols: (a) AgNO3 salts dissolution in HF/H2O leading to the precipitation of Ag nanoparticles onto the Si bulk substrate; (b) Ag dendrite formation due to Ag+ ions clustering onto the initial Ag particle seeds. Reprinted from ref. [48]. SEM images of the Ag dendrite samples in cross-section and in plan-view are reported in (c) and (d), respectively.
