Abstract
We deposited a submonolayer of potassium on stepped (755)[=6(111)×(100)] surfaces of copper and nickel in order to fabricate one-dimensional (1D) atomic-chain structures. Upon deposition of 0.09-ML potassium, we obtained 1D atomic chains on Ni(755) but not on Cu(755) as revealed from the low-energy-electron-diffraction(LEED) patterns. The difference in potassium structure has been attributed to the difference in interaction of potassium adsorbates with terraces and steps of the substrates. [DOI: 10.1380/ejssnt.2006.494]
