| 摘要 |
Methods are described for stoichiometric or cyclical re-hydrogenation of silicon, nanodiamond, or nanocarbon surfaces using hydrocarbons as sources of hydrogen. A method includes forming reactive sites on an adsorbate-substrate by non-thermal, non-electronic resonant photodesorption of a gas from the adsorbate-substrate; reacting the reactive sites with a functional radical; and cyclically repeating the steps of forming and reacting. The gas includes hydrogen and reacting includes re-hydrogenation of the reactive sites, the functional radical includes a hydrocarbon, the adsorbate-substrate is selected from silicon, nanodiamond or nanocarbon and resonant photodesorption includes a vibrational stretch mode.
