Notes. Dissociation energies (Dj), branching ratios (Γj), fitting parameter, A, with a dimension of (10−8cm3s−1eV−n), n is dimensionless, and the activation energy is Eact (eV) for the cations dissociating from SiC, σmax(E) is the maxima of our calculated cross-section in 10−16 cm2 and the incident energy (E) in eV.
