概要
- 論文の詳細を見る
Barrier-height imaging with scanning tunneling microscopy (STM) is applied to the study of oxygen adsorption on a Si(111) 7×7 surface. On clean surfaces, atomic resolution is obtained in the barrier-height mode, as expected for corrugated surfaces. Upon exposure to oxygen, the barrier height φ is found to increase at the oxygen-reacted sites. The dark sites show a greater increase in φ than the bright sites, indicating more charge trarnsfer at the dark sites.
