AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The first quant. evidence for the viability of three-dimensional arom. clusters involving d-orbitals in pseudo-octahedral coinage metal cages M6Lie2 (M = Cu, Tag, Au) as well as in tetrahedral coinage metal cages M'4Li4 (M' = Cu, Ag) was obtained computati ...
An extensive redistribution of spin density in TBrPP-Co molecules adsorbed on a Cu(111) surface is investigated by monitoring Kondo resonances at different locations on single molecules. Remarkably, the width of the Kondo resonance is found to be much larg ...
In plane wave based electronic structure calcns. the interaction of core and valence electrons is usually represented by at. effective core potentials. They are constructed in such a way that the shape of the at. valence orbitals outside a certain core rad ...
In this work we apply in a systematic way our multi-determinantal model to calculate the fine structure of the whole atomic multiplet manifold. The key feature of this approach is the explicit treatment of near-degeneracy correlation using ad hoc configura ...
The present invention exploits the impact ionization induced by drain voltage increase and the onset of a bipolar parasitic in an Omega-gate field effect metal oxide insulator transistor (called PI-MOS), in order to obtain a memory effect and abrupt curren ...
Isostructural clusters exhibit contrasting magnetic properties when the no. of electrons differs. Surprisingly, the same is true even for isoelectronic cages (e.g. Oh B6H62- is diatropic, whereas Oh Si62- is paratropic) or for those with different substitu ...
The nature of the bonding in ethylene and h2-P4 complexes, M(C2H4)2+ and M(h2-P4)2+, of group 11 metal cations (M = Cu, Ag, Au) has been explored by d. functional calcns. On the basis of the evaluation of symmetry orbitals, the contributions from the inter ...
We propose a new scheme to systematically design optimized connection atoms for arbitrary quantum mechanics/mol. mechanics (QM/MM) boundaries: the pseudopotential of the boundary atom is optimized such that it minimizes the errors in the electronic structu ...
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 ...
To accelerate reactive events in mol. dynamics simulations we introduce a general bias potential scheme which depends only on the electronic degrees of freedom of the reactive system. This electronic reaction coordinate, which is expressed in terms of a pe ...
