概要

• 論文の詳細を見る

• Spatial variation of local work function has been investigated for the Au/Cu(111) and Pd/Cu(111) systems using scanning tunneling microscopy (STM). While the measured work function of the Au adlayer is in the range between the Au(111) and Cu(111)'s values consistent with the results obtained by others, the work function on the Pd adsorbate shows a marked difference. The work function of the first Pd layer exceeds that of the Pd(111) surface and it increases further on its second layer, suggesting an overshooting (possibly oscillatory) behavior, which has never been reported experimentally.local work functionscanning tunneling microscopysurfacegoldcopperpalladium
