The objective of this work is a study of the structural properties (lattice parameters, total energy, bulk modulus) and electronic properties (band structure, density of states) of rare earth monochalcogenides LaX (X=Se, ...

La structure électronique des VC est fondamentalement intéressante et technologiquement import ante. Avec le code de simulation WIEN2k, nousavons effectué des calculs de propriétés électroniques en utilisant la théorie de ...

For the preparation of purification elements in our daily life at low cost, thin layers of zinc oxide and ZnO doped with copper (0%, 4%, 6%) were deposited on pellets of ceramics constituted Cristobalite, mullite and zircon. ...

In this work, we have made a parallel study using both powders and thin layers of TiO2 doped by copper (Cu). Annealing temperatures effects and the Cu dopant concentration on the phase composition, chemical banding and ...

Cuprous oxide (Cu2O) is a well-known oxide semiconductor with a band gap of 2.1 eV and a natural p-type conductivity, which is an attractive material for device applications because of its abundant availability, non toxicity, ...

Undoped TiO2, 3 and 5 at.% Cd-TiO2 thin films are prepared on glass substrate by sol–gel dip-coating technique. The structural, morphological and optical properties of the films have been investigated by X-ray diffraction ...

The arsenic clusters have been the topic of many experimental and theoretical studies [1-3].The mean reasons of this interesting subject are that arsenic has found wide applications in many fields, such as semiconductors, ...

Les travaux de recherche se sont orientés vers les semi-conducteur III-V, nous nous somme intéressé plus précisément aux deux systèmes GaAs et InAs, car ces derniers présentent des propriétés intéressantes commela haute ...

The Zirconium is the major component of zircaloy (2 and 4), this latter has a very weak thermal neutron absorption, satisfactory mechanical properties and good corrosion resistance at high temperature. For these reasons, ...

As an n-type semiconductor, hematite (α -Fe2O3) has attracted a great deal of attention from researchers in different fields because of its nontoxicity, low cost, high stability under ambient conditions, and multiple ...
