The amorphization of crystalline silicon by ball milling
As an industrially scalable process, ball milling is an important method of making nanocrystalline and amorphous silicon. At the lab-scale ball milling is typically conducted in so-called high energy ball mills (HEBM) e.g. a SPEX mill or in planetary mills [[11], [12], [13], [14]].Here we define HEBM as those milling conditions with impact energies >20 J.
