In this paper we reported room temperature synthesis of embedded porous Si (PS) based structures using simple and low cost techniques of electrochemical etching and thermal evaporation. PS was prepared by anodization of Si wafer in ethanoic hydrofluoric acid (HF). The Ge and ZnO layers were deposited onto the PS by conventional thermal evaporation. Three samples prepared namely PS, Ge/PS and ZnO/Ge/PS...
