Journal ArticleDOI
Investigation of electrical and dielectric properties of antimony oxide (Sb2O4) semiconductor thin films for TCO and optoelectronic applications
B. Ouni,M. Haj Lakhdar,R. Boughalmi,T. Larbi,A. Boukhachem,A. Madani,Karem Boubaker,Mosbah Amlouk +7 more
TL;DR: In this article, the electrical properties of Sb2O4 thin film were investigated using impedance spectroscopy technique in the frequency range 5-13MHz at various temperatures (325-450°C).
Journal ArticleDOI
Nickel content effect on the microstructural, optical and electrical properties of p-type Mn3O4 sprayed thin films
TL;DR: In this article, the direct band gap energy exhibits a red shift from 2.23 to 1.87 eV with Ni doping, and the dependence of both σAC and s with temperature and frequency agrees well with the CBH model as suggested by Elliott.
Journal ArticleDOI
Ethanol sensing properties and photocatalytic degradation of methylene blue by Mn3O4, NiMn2O4 and alloys of Ni-manganates thin films
TL;DR: In this article, the sensitivity properties of thin films based on nickel manganese oxides (Ni Mn O) which were grown by the spray pyrolysis technique on glass substrates at T = 350°C were highlighted.
Journal ArticleDOI
Temperature dependence of Raman spectra and first principles study of NiMn2O4 magnetic spinel oxide thin films. Application in efficient photocatalytic removal of RhB and MB dyes.
TL;DR: NiMn2O4 thin film can be used as a potential solar-light-driven photocatalyst and phonon dynamic behavior is well described by a model taking into account explicit lattice anharmonicity associated to both cubic and quartic phonon decay processes and thermal expansion related quasiharmonicity.
Journal ArticleDOI
Density functional theory study of ferromagnetically and ferrimagnetically ordered spinel oxide Mn3O4. A quantum mechanical simulation of their IR and Raman spectra
T. Larbi,Klaus Doll,T. Manoubi +2 more
TL;DR: In this paper, a combined theoretical and experimental investigation concerning the magnetic semiconductor Mn 3 O 4 is presented, where the absorbance spectra with ultraviolet-visible spectrophotometry in the near infrared region (UV-Vis-NIR) using a spectrophoton technique, and deduced this way the band gap.
