WebbCoordination Number (CN) is the number of nearest neighbors that each atom has. In a face-centered cubic crystal, each atom has 12 nearest neighbors (NN). That’s the … WebbHole polarons and defect-bound exciton polarons in lithium niobate are investigated by means of density-functional theory, where the localization of the holes is achieved by applying the +U approach to the oxygen 2p orbitals. We find three principal configurations of hole polarons: (i) self-trapped holes localized at displaced regular oxygen atoms and …
Webb11 apr. 2024 · In this Letter, we determine the lattice parameters of 100-nm-thick Sc x Al 1−x N ( 0 ≤ x < 0.25) layers grown on GaN by PAMBE. For a reliable determination of the Sc content x of the layers, we employ two independent analytical techniques, namely, x-ray photoelectron spectroscopy (XPS) and energy-dispersive x-ray spectroscopy (EDX).

The PEF simulations generated lattice parameters of a = 8.68, b = 2.58, and c = 4.44 Å , which also agree well with the UEF and experimental values.
WebbWe consider pairing in a two-component atomic Fermi gas, in a three-dimensional optical lattice, when the components have unequal densities, i.e. the gas is polarized. We show that a superfluid where the translational symmetry is broken by a finite Cooper pair momentum, namely a Fulde–Ferrel–Larkin–Ovchinnikov (FFLO)-type state, minimizes …
