Structural properties of AuNPs/PSi nanostructure
Digest Journal of Nanomaterials and Biostructures, 2022 Nanostructure porous silicon (NPSi) was achieved by electrochemical etching. A p-type silicon of resistivity (0.1-0.02 Ω.cm) and n-type silicon of resistivity (1.5-4 Ω.cm) were immersed in 25% HF at etching time of 15 min and fixed current density 20mA/cm2 . Moreover. A gold nanoparticles were produced by laser ablation of energy (250, 350 and 450 mJ).
