Abstract
The ordered c(2 x 2) phase of Sn atoms on the Ni(100) surface was studied by constant-energy-loss electron-energy-loss holography (CEL-EELH). Three-dimensional images at an atomic level around adsorbed Sn atoms of the surface were deduced. The results clearly favour a chemisorption geometry with Sn atoms incorporated into the first Ni layer, and demonstrate the ability of the CEL-EELH technique to give atomic images similar to those obtained by synchrotron radiation holography.
