Abstract : Molecular beam studies with hydrogen have uncovered a mechanism for promoting the interaction with a semiconductor surface through stimulation of the gas stream alone. Field emission observations of an atomically smooth f.c.c. metal have been carried out. These reveal a pronounced structural specificity for inert gases--rough, index planes are preferred both in van der Waal's and in weak chemical interactions. (Author)
