Title: METHOD FOR SELECTIVELY REMOVING HYDROGEN FROM MOLECULES
Abstract:
Methods for removing hydrogen from molecules are disclosed. In one embodiment, hydrogen-containing molecules are deposited on a solid substrate and are bombarded with hydrogen projectile particles. The particles may have energies of 5-100 eV, or more preferably 10-50 eV. The hydrogen projectile particles remove hydrogen atoms from the deposited molecules while they are on the substrate, without removing other atoms from the molecules. Dangling bonds are created by the loss of hydrogen and can be used to cross-link the molecules. The resulting product can be a nanometer-thick dense film.
