NMR parameters of Ge-73 and O-17 in vitreous GeO2 and quartz GeO2, including the isotropic shifts, the quadrupole coupling constants C-Q, and the electric-field-gradient asymmetry parameters., are determined through density functional calculations. Clear c ...
Tuning of effective band gaps at insulator surfaces by adsorbed molecules is of fundamental interest but also technologically relevant for contact charging induced by adsorbed molecules like hydroxybenzoic acids. Our studies by density functional theory of ...
Based on density functional theory, the electronic and optical properties of hybrid organic/perovskite crystals are thoroughly investigated. We consider the monocrystalline 4F-PEPI as material model and demonstrate that the optical process is governed by t ...
Calculations of formation energies and charge transition levels of defects routinely rely on density functional theory (DFT) for describing the electronic structure. Since bulk band gaps of semiconductors and insulators are not well described in semilocal ...
We use angle-resolved photoemission spectroscopy to study bandwidth renormalization in layered superconductor 2H-NbSe2. Renormalization of the conduction band in comparison with the very similar 2H-TaSe2 is of the factor of two. We discuss the possibility ...
An atomistic model of substoichiometric germanium oxide is generated through ab initio molecular dynamics. The resulting structure shows a predominance of threefold coordinated Ge and O atoms. We also generate substoichiometric models through bond-switchin ...
3d metal K-shell X-ray absorption spectra of perovskites with the composition La1-xCaxCoO3-delta (x=0, 0.2, 0.4, 0.5, 0.6, 0.8), La1-xSrxCoO3-delta (x=0, 0.1, 0.2, 0.3, 0.4, 0.5) and La1-xSrxFeO3-delta (x=0, 0.2, 0.4, 0.5, 0.6, 0.8) are compared on the bas ...
The electronic band structure and Fermi surface of ZrTe3 was determined by angle-resolved photoemission spectroscopy. Several bands and a large part of the Fermi surface are found to be split by 100-200 meV into two parallel dispersions. Calculations of th ...
Here we present a calculation of the temperature-dependent London penetration depth, λ(T), in Ba1-xKxFe 2As2 (BKFA) on the basis of the electronic band structure (Zabolotnyy et al 2009 Nature 457 569, Zabolotnyy et al 2009 Physica C 469 448) and momentum-d ...
At the surface of a solid, quantum mechanics allows the existence of two-dimensional Bloch waves as solutions of the Schrödinger equation. These "surface" states are interesting both for fundamental and practical reasons, and have been extensively explored ...
