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 ...

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 ...

Nanotubes are of great interest due to their high surface-to-volume ratios and size-dependent properties. Titanium dioxide nanotube array is a well-known nanostructured semiconductor oxide with improved functional ...

In this work, we studied the radiation damage induced by the implantation of Sb+ ions into Si(111) targets at 120KeV energy to a dose of 1E15Sb+/cm2 and 1.6E15Sb+/cm2. The restoration of defects by the annealing treatments ...

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, ...

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 ...

We calculated structural, electronic, and thermodynamic properties of paramagnetic post-perovskite NaIrO3. Our calculations were done in the framework of the density functional theory (DFT), using the full potential-linearized ...

Rare-earth oxides as Y2O3 and La2O3 evenly dispersed in Fe matrix constitute ODS alloys with potential applications in nuclear power plants .Dispersion of the above oxides can be obtained from various synthetic routes. ...

This work is a review of the application of Raman spectroscopy to identify the nature of some carbon materials such as: commercial graphite with various compositions. The RAMAN spectra show four bands D, G, D’ and 2D bands. ...
