Figure 6From: Fabrication of porous silicon nanowires by MACE method in HF/H2O2/AgNO3 system at room temperatureAg particle migration in bulk Si driven by self-electrophoresis mode. An electric field is built with the presence of H+ gradient across the Ag particle from the anode site to cathode site, which can propel Ag particles toward the anode site.Back to article page
