    Abstract: 在此實驗中我們研究氫原子在銀薄膜表面的吸附與脫附行為。首先,我們在金(111)表面成長原子級平坦的銀薄膜。這些銀薄膜在低溫下曝露在熱裂解的氫原子束中,然後升溫讓氫原子脫附。實驗過程中,運用光電子能譜術來監看薄膜的表面態,以檢測薄膜表面的演變。實驗結果顯示,銀薄膜表面態會因低溫曝氫而嚴重衰減,但表面態會在樣品溫度回升時部分復原。此外,我們也探討了薄膜表面態衰減與復原溫度與薄膜厚度之間可能的關聯。;We have studied the adsorption and desorption of atomic hydrogen on the surfaces of Ag thin films. Atomically flat Ag films were grown on Au(111), exposed to a flux of thermally generated hydrogen atoms at a low sample temperature, and annealed for the desoprtion of hydrogen atoms. During annealing, the evolutions of the surfaces of the thin films were characterized on monitoring their surface states with angle-resolved photoemission spectroscopy. Our experimental results showed that, with the exposure of hydrogen atoms, the surfaces states of thin Ag films deteriorated severely, and the surface states recovered only partially during annealing. In addition, we also investigated the relationship between the deterioration of the surface states and the thickness of the thin films.
