Electronic structure of atomic chains on vicinal Si „ 111 ... - Au
Unusual electronic states are found for gold-induced chain and ladder structures on vicinal Si~111! surfaces, such as Si(111)532-Au and Si~557!-Au. As two-dimensional reference the Si(111)A33A3-Au surface is investigated. The highly stepped Si~557!-Au surface is metallic, despite an even electron count. That is explained by two half-filled, nearly degenerate bands. On the Si(111)532-Au surface ...
متن کاملمحاسبه سطح مشترک (111)Pb/Si با استفاده از نظریه تابعی چگالی
Work function and surface energy per unit area were calculated in the framework of density functional theory (DFT) with Linearized A ug mented Plane Wave Plus Local Orbital method in full potential for a clean symmetric slab of silicon containing two (top and bottom) surfaces. The surfaces were theoretically modeled using supercell technique by stacking a variety of silicon layers along (111)...
متن کاملStudy the stability of Si, Ge, Fe and Co in the interior surface of metallic carbon nanotube for hydrogen storage
In this article, we have performed calculations for studying the stability of the carbon group elements such as Si and Ge and also the magnetic elements like Fe and Co via first principle investigations. We found that Si and Ge decoupled from the interior surface of carbon nanotubes, this fact was independent in curvature, radius, conductivity and numbers of atoms in the carbon nanotubes. But t...
متن کاملCONTROL OF CHAOS IN A DRIVEN NON LINEAR DYNAMICAL SYSTEM
We present a numerical study of a one-dimensional version of the Burridge-Knopoff model [16] of N-site chain of spring-blocks with stick-slip dynamics. Our numerical analysis and computer simulations lead to a set of different results corresponding to different boundary conditions. It is shown that we can convert a chaotic behaviour system to a highly ordered and periodic behaviour by making on...
متن کاملAdjustable Plasmonic Bandgap in One-Dimensional Nanograting Based on Localized and Propagating Surface Plasmons
Compared to the long history of plasmonic gratings, there are only a few studies regarding the bandgap in the propagation of plasmonic surface waves. Considering the previous studies on interpretation of plasmonic bandgap formation, we discuss this phenomenon using the effect of both surface plasmon polariton (SPP) and localized surface plasmon (LSP) for our fabricated one-dimensional metallic-...
