Hydrocarbon radicals interaction with amorphous carbon surfaces

Total reflection coefficients and break-up patterns for incident atomic carbon, C2, CH, CH2, CH3, CH4, C2H, C2H2, C2H3, C2H4, C2H5 and C2H6 from an amorphous hydrocarbon surface with a H:C ratio of 0.66 are calculated using the HCParcas molecular dynamics code with an empirical Brenner potential. Incident molecules are separately equilibrated at incident energies ranging from thermal up to the maximum energies at which the molecules can be structurally stabilized to mimic the conditions in an equilibrium plasma.
