Enhanced electron-electron correlations in nanometricSrRuO3epitaxial films

Band-Gap Tuning Of Electron Beam Evaporated Cds Thin Films

The effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated CdS thin films have been investigated. CdS thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and Atomic Force Microscopy were used to character...

ELECTRON CORRELATIONS IN THE HIGH Tc-COMPOUNDS

Ab-initio correlation results for an idealized high Tc-compound are compared to density functional (DF) calculations for the same system. It is shown that and why the DF-charge distribution is wrong. The largest deficiency arises for the Cu-dx2−y2-occupation, arising from strong atomic correlations but mostly from anomalous neighbor Cu-spin correlations. Both features are beyound the range of t...

Electron correlations in multiconfiguration atomic wave functions.

A two-electron spin-independent operator is defined to represent the spatial correlation of the electrons in a general atom or ion. The spherical-tensor expansion of this operator provides a systematic method for evaluating the two-electron correlation function implied by a Hartree-Fock N-electron wave function including arbitrary configuration mixing. The method is illustrated by examples invo...

Electron Correlations in Narrow Energy Bands

Correlations in the Layered Electron Gas

The self-consistent theory of Singwi, Tosi, Land and Sjolander (STLS), which accounts for exchange and short-range correlation effects through an effective potential depending on the structure factor, is generalized to the Visscher and Falicov model of the layered electron gas. The complete numerical solution of the STLS self-consistent equations provides information about intraplane and inter...
