Semiconductor Surface Chemistry.
Abstract
As a result of the studies under this grant, four important aspects of the interactions between molecular gases with crystals have been clarified: (1) Chemisorption of hydrogen on perfect low-index planes of both an fcc material, rhodium, as well as of a bcc metal, tungsten, has been investigated for the first time. (2) It has been established that decomposition of a polyatomic molecule can be brought about at a cold surface merely by thermal excitation of the gas. (3) Diffraction of beams of hydrogen molecules has for the first time been observed from ionic crystals with a (111) surface, as well as from an oxide. (4) The binding site of a metal atom on its own crystal lattice has been established.
