Surface X-ray diffraction experiments have been performed on the K-induced super structures on Ag(00 1). Both, the (2 Γ 1) and the (3 x 1) superstructure which are formed at K-coverages of about 0.15 and 0.30 ML, are found to consist of missing row type reconstructions, where one and two Ag-rows are
The geometric structure of the DNA-base derivative 5-Chlorouracil deposited on Ag(1 1 1) was analyzed using surface X-ray diffraction. Although the ad-layer structure bears many similarities with its bulk analog (e.g., lattice metric, hydrogen bonded molecules within each molecular layer and van der
