Web13 apr. 2024 · We analyze the possibility to realize a localized surface plasmon resonance in metamaterials composed of As1−zSbz nanoparticles embedded in an AlxGa1−xAs1−ySby semiconductor matrix. To this end, we perform ab initio calculations of the dielectric function of the As1−zSbz materials. Changing the chemical composition z, we trace the evolution … WebWe examined the propagation of an infectious disease and the eventual extinction of the host population in a lattice-structured population. Both the host colonization and …

WebThe simple cubic (SC) unit cell can be imagined as a cube with an atom on each corner. This unit cell is the simplest for people to understand, although it rarely occurs in nature due to its low packing. SC has 1 atom per unit cell, lattice constant a = 2r, Coordination Number CN = 6, and atomic packing factor APF = 52%. WebEvolutionary Lattice Model The relative importance of exogenous and endogenous effects in extinction has been widely debated. We present a unifying picture based on a biotic …
