Photochemical depassivation of hydrogenated (100) nitrogen surface of cubic boron nitride
Abstract
The passivation of nitrogen top-layered (100) surface of cBN by hydrogen was theoretically predicted to be related to the difficulty of chemical vapor deposition of cubic boron nitride recently. The possibility of photochemical depassivation of this surface was suggested by the anti-bonding nature of the surface H-N bonds at the lowest unoccupied molecular orbital; that was demonstrated by AM1 molecular orbital calculations using large cBN clusters such as B{sub 30}N{sub 32}H{sub 64}{sup (2+)} and B{sub 30}N{sub 32}H{sub 62}(2BH {sub 3}). {copyright} {ital 1997 Materials Research Society.}
