The chemical dynamics of XeF₂ and Xe(F₂) reactions with Si(100)
The chemistry of fluorine, F2, and xenon difluoride, XeF2, with clean Si are nearly indistinguishable. Both species react via the atom abstraction mechanism, whereby a surface dangling bond abstracts a F atom from the incident molecule, scattering the complementary F atom or XeF fragment into the …
