Abstract:

AbstractWe determined the c(52 × 2)R45° adlayer structure formed on Ni(001) by Li deposition at 230 K using a dynamical low energy electron diffraction (LEED) analysis with symmetrized automated tensor LEED. It is an antiphase c(2 × 2) domain structure, in which all Li atoms occupy the hollow sites of the Ni(001) surface at coverage 0.6. This antiphase domain structure is very similar to the previously determined c(52 × 2)R45° formed on Cu(001) by Pb deposition.
