Effect of quantum confinement of surface electrons on an atomic motion on nanoislands (2008)

Smirnov, A. S., Negulyaev, N. N., Niebergall, L., Hergert, W., Saletsky, A. M., Stepanyuk, V. S.

Ab initio calculations and kinetic Monte Carlo simulations demonstrate that the quantum confinement of surface electrons to nanoislands can significantly affect the growth process at low...

Onset of Magnetic Order in Strongly-Correlated Systems from ab initio Electronic Structure Calculations: Application to Transition Metal Oxides (2008)

Hughes, I. D., Daene, M., Ernst, A., Hergert, W., Lueders, M., Staunton, J. B., ...

We describe an ab initio theory of finite temperature magnetism in strongly-correlated electron systems. The formalism is based on spin density functional theory, with a self-interaction corrected...

Ab initio study of mirages and magnetic interactions in quantum corrals (2005)

Stepanyuk, V. S., Niebergall, L., Hergert, W., Bruno, P.

The state of the art ab initio calculations of quantum mirages,the spin-polarization of surface-state electrons and the exchange interaction between magnetic adatoms in Cu and Co corrals on Cu(111)...

Self-interaction correction in multiple scattering theory (2004)

Lüders, M., Ernst, A., Däne, M., Szotek, Z., Svane, A., Ködderitzsch, D., ...

We propose a simplified version of self-interaction corrected local spin-density (SIC-LSD) approximation, based on multiple scattering theory, which implements self-interaction correction locally,...

Ab initio approach for atomic relaxations in supported magnetic clusters (2004)

Stepanyuk, V. S., Klavsyuk, A. L., Niebergall, L., Saletsky, A. M., Hergert, W., Bruno, P.

We present a newly developed scheme for atomic relaxations of magnetic supported clusters. Our approach is based on the full potential Korringa-Kohn-Rostoker Green's function method and the second...

Long-range electronic interactions between adatoms on transition metal surfaces (2004)

Stepanyuk, V. S., Niebergall, L., Baranov, A. N., Hergert, W., Bruno, P.

Ab initio calculations of surface-state mediated interactions between Cu adatoms on transition metal surfaces are presented. We concentrate on Co/Cu(111) and Co(0001) substrates and compare results...

Resonant inelastic x-ray scattering (RIXS) spectra of magnesium diboride (2003)

Kokko, K., Kulmala, V., Leiro, J. A., Hergert, W.

Using the tight-binding linear muffin-tin orbitals method, the soft x-ray fluorescence K-emission spectra of boron in MgB_2, excited close to the absorption edge, are estimated. In the calculations...

Prediction of a new class of half-metallic antiferromagnets (2003)

Kodderitzsch, D., Hergert, W., Szotek, Z., Temmerman, W. M.

We report on vacancy induced half-metallicity in the prototype Mott-insulating substances MnO and NiO. By embedding a cation-vacancy into a magnetic system a new road opens up to the construction of...

DISCUSSION OF THE CONVERGENCE PROPERTIES OF THE PERTURBATION SERIES USED IN THE CALCULATION OF EBIC- AND CL-CONTRASTS (1991)

Hergert, W., Pasemann, L., Hildebrandt, S.

For the calculation of the contrast of a defect in semiconducting material, the defect is regarded as a bounded region where the minority carrier lifetime τ' is lower than that (τ) outside...

RECENT RESULTS IN THE THEORETICAL DESCRIPTION OF CL AND EBIC DEFECT CONTRASTS (1991)

Hildebrandt, S., Schreiber, J., Hergert, W.

The theoretical description used for the analysis of beam-voltage dependent CL and EBIC contrasts from a surface-parallel dislocation is summarized. The importance of the use of a realistic carrier...
