We determined the local adsorption structure of disordered oxygen on the Ni(1 1 1) surface by means of diffuse holographic LEED. The measurements have been performed above the critical temperature (Tc ¼ 450 K) for the oxygen order–disorder phase t

Experimental studies of the phase transitions in the adsorption system Li/Mo~112! are presented. This system is a model system for highly anisotropic interactions. From measurements of the half-widths of the low-energy electron diffraction spot profi

Alkali and earth alkali metals like Li and Sr adsorbed on the furrowed substrates Mo(211) and W(211) tend to form chain structures (1×n). These chains are oriented normal to the furrows, and n can reach values up to 8. In order to clarify the nature

The local geometries of Li adsorbed on the furrowed (211) surface of Mo have been investigated by a LEED-IV analysis using an energy of 30–180 eV. Adsorbate-induced lateral interactions mediated mainly through the substrate turn out to be mainly re

The phase diagram of Te on face-centred cubic Pd(100) has been determined by means of high-resolution spot profile analysing low-energy electron diffraction. We found two types of ( 5 × 5 ) n R 27° structure with one ( n =1) and two ( n =2) atoms p

The surface structures of face-centered-cubic Pd(210) and body-centered-cubic Mo(211) have been determined by low energy electron diffraction (LEED). We find substantial relaxations (with respect to the bulk layer separation) of the interlayer distan

The local geometrical structures of the p(2 × 2) and c(2 × 2) phases of S Pd (100) as well as of the p(2 × 2) structure of atomic oxygen on the same surface were determined by LEED- IV analysis using the energy range between 35 and 350 eV. The tot
