The characteristics of the porous Si layer formed by silver enhanced chemical etching of p-Si in aqueous HF/HNO3 solution are influenced by the concentration of Ag ions in the plating bath, the concentrations of both the etchant (HF) and the oxidizing agent (HNO3), and the etching time of the Si substrate. The SEM outcomes confirmed that deposition of silver ions from 1.0 × 10-3 M AgNO3 solution on p-Si before the chemical etching in HF/HNO3 resulted in uniformly PSL in a comparison with the other silver nitrate concentrations. The impedance data revealed that when the concentrations of HF an...
