Abstract
The abstraction of chemisorbed deuterium (D) on Si(100) by atomic hydr ogen (H(at)) is studied in real time. The surface H and D coverages ar e measured by mass analyzing the recoiled H+ and D+ ion signals during the abstraction reaction. We find that H(at) efficiently removes adso rbed D on Si(100) with a low activation energy of 0.8+/-0.6 kcal/mol a nd a reaction probability that is 0.36 times the H(at) adsorption rate on clean Si(100).
