| Outline of Final Research Achievements |
An environmental reflection high-energy electron diffraction (ERHEED) apparatus with 2-stage lens and differential pumping system on both of incident and exit sides were developed, which is aimed to analyze surface crystalline structures under gas pressure. The exit side lens system could not operate properly, however, incident side lens system worked as designed and it was demonstrated that the developed ERHEED can obtain beam rocking patterns in gas atmosphere that is more than one order of higher pressure than conventional differential pumped RHEED system. With this new equipment, in-situ structural analysis of the reacting surfaces such as chemical vapor deposition and catalytic reaction becomes possible. Thus it is expected to be contribute to the development of novel materials.
