Synthesis and characterization of porous silicon as hydroxyapatite host matrix of biomedical applications

In this work, porous-silicon samples were prepared by electrochemical etching on p-type (Bdoped) Silicon (Si) wafers. Hydrofluoric acid (HF)-ethanol (C2H5OH) [HF:Et] and Hydrofluoric acid (HF)-dimethylformamide (DMF-C3H7NO) [HF:DMF] solution concentrations were varied between [1:2]-[1:3] and [1:7]-[...
