Fundamental Studies of the Structure and Chemistry of Solid Surfaces.
Abstract
Decomposition of hydrazine has been studied on Ir(111) from temperatures below 200k up to 1500k using a supersonic molecular beam scattering system. The decomposition begins around 200k producing nitrogen, ammonia, and hydrogen. An extremely strong angular dependence was found for nitrogen. This is the first time normally directed emission of nitrogen has been observed for surface decomposition. A Fourier transform of the entire waveform has been utilized to deduce the details of the decomposition mechanism. Photoemission from hydrazine and ammonia on Ir(111) using high intensity polarized UV radiation has been investigated. The results are consistent with the data from the scattering experiments. AES was used to monitor the absorption of oxygen on Al(111) surfaces and was found to be dependent on both time and oxygen pressure. Further studies will concentrate on the kinetics of aluminum oxidation. (Author)
