Abstract
The abstraction of chemisorbed hydrogen on the Si(100) surface by atom ic deuterium has been studied by direct observation of the reaction pr oducts HD. The angular distribution of the HD yield is found to be shi fted towards the specular direction of the incident D atoms by about 2 0 degrees with respect to the surface normal. The strong forward HD de sorption is compared with the thermally associative desorption of D-2 peaking towards the surface normal. A direct Eley-Rideal mechanism is suggested for the D abstraction reaction of the chemisorbed H atoms on the Si(100) surfaces. (C) 1997 American Institute of Physics.
