The growthmechanism of Si nanowires from thermal evaporation of SiOpowders, however, is not fully understood. Thus, more detailed and systematic experimental ... length of the Si core is only one-third to one-half of the entire length of the wire, and the rest of the wire is pure amorphous silicon oxide.We also investigated the cross section of the hard...
