When confronted with Si-Si-Si and radicals in the same sentence, I
don't get comforted and definitely wouldn't characterize it as 'rather
There seem to be quite a number of publications referring to MD of
Si-Si systems though. Try googling a bit, or try Web of Science; gives
quite a number of hits which you could use to extract parameters.
However, do try to assess how reasonable the assumptions/calculations
in these papers are for determining the parameters.
