We have performed scanning tunnelling microscopy (STM) measurements of thin films of Co and CoPt alloys on Pt(1 1 1). In contrast to the interpretation of an earlier low energy electron diffraction investigation by Tsay and Shern [Surf. Sci. 396 (199

We use embedded atom method potentials to calculate the Schwoebel barriers for a large number of hopping and exchange processes of Pt and Ni adatoms descending steps of the Pt(1 1 1) surface. The barriers we find for hopping processes are too high to

Adsorption of oxygen on Al(111) is studied by scanning tunneling microscopy at 80 and 300 K. After adsorption at 130–195 K, STM images taken at 80 K show pairs of oxygen adatoms with interatomic distances mainly between one and three Al interatomic

Interlayer diffusion, i.e. mass transport between different terraces, is known to be an essential process for obtaining layer-by-layer growth, avoiding formation of three-dimensional (3D) islands when growing thin films. We present experimental resul

Interlayer diffusion of Co over steps of vacancy islands on the Pt(111) surface as studied by scanning tunneling microscopy is presented. It is demonstrated that Co atoms descend Pt steps by an exchange diffusion process at the step edge with the Pt

Using scanning tunneling microscopy, low-energy ion scattering, and quantitative low-energy electron diffraction, we find about $17%$ metal vacancies on the oxygen-covered Cr(100) surface. The oxygen atoms occupy all the hollow sites of the first lay

We report a scanning tunneling microscopy (STM) study of the rutile TiO2(110) surface. The surface was prepared by sputtering and annealing in an ultrahigh vacuum (UHV). After annealing to 1100 K in UHV, a (1×1) surface with a terrace width of ∼10

Scanning tunneling microscopy was used to study the initial stages of Cl2 adsorption on TiO2s110d. Cl atoms adsorb on the rows of fivefold coordinated surface Ti atoms, and mostly form well separated pairs (average distance 26 A, atoms can be two or

We report about a feasibility study regarding multivariate test data monitoring. Since electrical test data (e.g. wafer sort data) consist often of dozens of correlated parameters, the application of a multivariate yield control concept seems to be i
