Fig. 1From: High Seebeck Coefficient of Porous Silicon: Study of the Porosity DependenceEtch rate and porosity versus the anodization current density for two different electrolytes. The etch rate (a) and the porosity (b) as a function of the current density used in electrochemistry for two different electrolyte compositions are depicted.
