After high-energy wet ball-milling with Si nanoparticles, the intensity of the D band increased and the G band decreased to an I D /I G ratio of 0.97, as shown in the Raman spectrum of the Si/G composite. This result shows that the layered structure of EG was exfoliated and thinned, and more edges and defects were induced by the wet ball-milling.

1. As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. The powder of a material is taken inside the steel container.

The powders were milled for 1–18 h in a steel ball mill in argon. The approximate pressure imposed on particles was 2 GPa. The spectra of the as-milled powders were compared with the initial silicon. It was found from the Raman peak position shifts that milling generated strains in the silicon lattice, bringing about a transformation of cubic ...
