Atomic structure of the Eu/Si(111) 3x2, 5x1, and 7x1 surfaces studied by photoelectron spectroscopy periodicity is expected for the 5 × 1 and 7 × 1 reconstructions, which is in good agreement with the nonmetallic electronic structure of these phases... M Kuzmin,P Laukkanen,RE Peraelae,...

We conclude that these heavy p-block elements are interchangeable and that the electronic structure correspondence can be preserved regardless of elemental composition. This represents an extension of the traditional concepts of periodicity, where elements of similar valence configuration are grouped into ...
BpC+nions were observed in laser vaporization (Becker‐Dietze) and their emission intensities show very strong alternations against the number n of carbon atoms: they are maximum for even n if p=1, and for odd n if p=3. In addition, they show a four‐fold periodicity with strong enhanceme...
A semiconductor is a material with a moderate band gap (Eg < 3.5 eV), i.e., the energy difference between the valence band (VB) and the conduction band (CB) in its electronic band structure. From: Applied Materials Today, 2023
Theoretical and experimental electronic structure of quinacridone Although density functional theory is often used to study the frontier energy levels of organic electronic materials, standard functionals tend to predict too small fundamental gaps, may lead to wrong orbital energy ordering, and do not ....
Our calculations, based on density functional theory, show superstructures of periodicity (3 × 3) in the electronic structure of the surface. In good agreement with STM experiments, these superstructures show a variety of patterns with their intensity decaying away from the defect. Two kind of ...
For developing an accurate first-principles technique for describing the electronic structure of systems without perfect periodicity, we have performed self-consistent electronic-structure calculations for dilute alloys of 3d-transition-metal impurities in aluminum using the recursion method with the tight-bi...
Such regular oscillation also constitutes a natural occurrence of Floquet states with its electronic structure, and Hamiltonian exhibiting periodicity16. Dynamics of electron and atoms is simulated for 1200 fs by rt-TDDFT. We expect the regular oscillation will continue for a much longer time. In...
