Porous silicon (PSi) samples were prepared by electrochemical etching of silicon-on-insulator wafers, consisting of 45 m thick p-type (111) silicon epitaxial layer grown on a thin 100 nm SiO 2 layer on silicon substrates, by varying the concentration of 48% HF in ethanol solution. Within the epitaxi
Silicon-on insulator (SOI) wafers, consisting of 22 lm thick p-type silicon epitaxial layer grown on 280 lm thick n-type (1 1 1) silicon substrate, were electrochemically etched in hydrofluoric acid (HF) to produce porous silicon (PS) samples. The pores of different size and different depth were obt
