CHEMICAL-REACTION DYNAMICS OF F ATOM REACTION WITH THE DIMER RECONSTRUCTED SI(100)(2X1) SURFACE

We have calculated the initial sticking probability S0for near thermal atomic fluorine on the clean dimer reconstructed Si{ 100} (2x1) surface to be near unity using molecular dynamics simulations. The dependence of the sticking probability on coverage decreases to approximately zero for the fully fluorinated surface. The sticking probability of an F atom on a fully fluorinated silicon surface increases when the kinetic energy of the fluorine atom is above 0.50 eV. © 1990, American Vacuum Society.
