The LDA-1/2 method expands Slater's half occupation technique to infinite solid state materials by introducing a self-energy potential centered at the anions to cancel the energy associated with electron-hole self-interaction. To avoid an infinite summation of long-ranged self-energy potentials they must be trimmed at…

Two-dimensional (2D) perovskites with general formula $APbX_4$ are attracting increasing interest as solution processable, white-light emissive materials. Recent studies have shown that their broadband emission is related to the formation of intra-gap color centers; however, the nature and dynamics of the emissive spe…
Dans cette thèse, nous proposons une étude détaillée des mécanismes responsables de la perte de données dans les mémoires à changement de phase enrichies en germanium (Ge-rich PRAMs), à savoir la dérive de la résistance au cours du temps et la recristallisation de la phase amorphe. Nous commençons par une présentation…
The Mott-insulating distorted perovskite SmTiO$_3$, doped with a single SrO layer in a quantum-well architecture is studied by the combination of density functional theory with dynamical mean-field theory. A rich correlated electronic structure in line with recent experimental investigations is revealed by the given r…
Structure-based and source-based nomenclature rules are extended to regular double-strand (ladder and spiro) organic polymers. A doublestrand polymer is defined as a polymer the molecules of which are formed by an uninterrupted sequence of rings with adjacent rings having one atom in common (spiro polymer) or two or m…
We report on a new concept of cloaking objects in diffusive light regime using the paradigm of the scattering cancellation and mantle cloaking techniques. We show numerically that an object can be made completely invisible to diffusive photon density waves, by tailoring the diffusivity constant of the spherical shell…
In this work, we introduce two new subclasses S_{Σ_{m}}(α,λ) and S_{Σ_{m}}(\b{eta},λ) of Σ_{m} consisting of analytic and m-fold symmetric bi-univalent functions in the open unit disk U. Furthermore, for functions in each of the subclasses introduced in this paper, we obtain the coefficient bounds for |a_{m+1}| and |a…

Dental pulp stem cells (DPSCs) are stem cells found in the dental pulp. The ability of DPSCs to differentiate towards odontoblastic and osteoblastic phenotype was reported first in the literature, then in the following years, numerous studies on odontogenesis were carried out, starting from mesenchymal stem cells isol…
We present an investigation of the mechanical properties of Al2O3-ZrO2 as duplex-structured materials using the finite element method (FEM). The creation of stress fields are a result of the material trying to dissipate mechanical energy that is being exerted on the biomaterial. By finite element modelling and the str…
TiO2:SnO2 thin films were deposited on glass substrates, by using sol gel spin coating method with different ratio (3%, 5% and 7%) at 3200 rpm, to study their effect on different properties of TiO2: SnO2 thin films. The structural and optical properties of films have studied for different ratio. These deposited films…
The magnetic properties of MnP:GaP nanoparticles are calculated using a statistical mechanical approach and effect of various factors on magnetization of nanoparticles is studied. The calculation is based on solution of localized partition function and evolution of magnetic moment affected by thermal fluctuation and e…
We propose a compactly integrated transverse-magnetic (TM)-pass polarizer based on rectangular-shape onedimensional photonic-crystal silicon waveguide with an extremely high polarization extinction ratio of >30 dB and low insertion loss (~1 dB) over a broad wavelength range of 210 nm from 1,460 nm to 1,670 nm. The pol…
Libya proved to be a unique example of WMD elimination. Unlike other WMD elimination cases, which arose out of an armed conflict that resulted in an opportunity to access and destroy a WMD program, Libya began as a cooperative WMD elimination effort that took a turn after violence erupted. The first phases of eliminat…
The quest of higher conversion efficiencies of solar cells has led to the improvement of material properties and the design of new structures for a better use of the solar spectrum. One of the most promising thin-film silicon solar cell concepts is “Micromorph” tandem solar cells consisting of a microcrystalline silic…
Photoelectrical response in CuInS2–ZnIn2S4 alloys single crystals was analysed in the low temperature region from 30 K up to 100 K. The molar ratio of ZnIn2S4 in the alloys was varied in the range 0 mol%−16 mol%. The crystals with up to 12 mol% were the single-crystalline, meanwhile those with 16 mol% were the two pha…
