| Research Abstract |
Surface structures of silicon oxynitride and graphene on SiC(0001) and silicate on Mo(112) were determined by means of low-energy electron diffraction(LEED). Behaviors of alkali-metal atoms on graphene surfaces were also studied, and some of their structures were determined. The development of LEED probing surface small region was attempted, and LEED patterns of graphene surfaces were obtained successfully. Furthermore, fieldassisted gas etchings of tungsten tips under field-ion microscopic observation were examined, and atomically sharp tip apexes were achieved. Electron beams with small opening angles were obtained reproducibly from the tip.
