Research Abstract

The investigators developed a Time-of-Flight Fourier Transformed Ion Energy Analyzer for space-resolved and energy-resolved observation of products in electron-or photo-stimulated desorption. In the present project, a multi-functionalized ultrahigh vacuum system was built to observe the coordination, energy state, and structure of absorbed reaction intermediates, by combining the analyzer with an Reflection Absorption Infared Spectroscope (RAIRS) .
The RAIRS with a reaction chamber allowed us to observe in-situ surface reaction in atmospheric reactant ambient. The ion analyzer operated with pulsed electron beam enabled the detection of reaction intermediate in a time resolution as small as 20 ms.
As the developing the system, thermal and photo induced reaction of alkygallium compounds on a Si (111) - (7*7) surface was studied by scanning tunneling spectroscopy (STM) . The decomposition of individual trimethylgallium and triethylgallium molecule was imaged. The manipulation of adsorbed formate, a simple organic molecule, was also successfully examined on TiO_2 (110) .
