Microstructural evolution of oxides and semiconductor thin films

Nickel content effect on the microstructural, optical and electrical properties of p-type Mn3O4 sprayed thin films

“…These peaks match well with Mn 3 O 4 material [31]. Indeed, the sharp peak at 655 cm -1 , characteristic of the tetragonal [32][33]. The intensity of these peaks decreases with Ni content which is may be due to local vibrations of Ni element in Mn 3 O 4 thin films.…”

“…However, the microstrain ( ε ) decreases by increasing Ni content up to 2% and then it increases which confirm the formation of a well-oriented structure for the sample doped with 2% at Ni [30]. Moreover, the Raman spectroscopy is used to reach more information about the microstructure and the lattice defects.…”

Pure and zirconium-doped manganese(II,III) oxide: Investigations on structural and conduction-related properties within the Lattice Compatibility Theory scope

“…In the actual case, the systematic distortion which results from Mn ions dissymmetry seems to be balanced by the presence of Zirconium ions. In this context, it can be presumed that zirconyl ion ZrO 2 þ acts on the shortest O-metal bonds, shifting them from basically and Chen et al [55][56][57]. The last works introduce similar preparation methodologies and characteristics of Mn 2 O 3 and Mn 3 O 4 nanocrystals with a major advantage of yielding nanoparticles, nanowires, nanorods, and nanofractals rather than thin films.…”

Epitaxial Growth of Multi-structure SnO2 by Chemical Vapor Deposition

“…The research has been focusing on the development of morphologically controlled SnO 2 nanostructures through different methods, such as thermal evaporation, solutionbased synthesis and template-assisted methods [11]. The thermal evaporation process is evaporating a stock and transferring to a substrate to form designed structure by using catalyst or through self-assembling process [12,13]. Trung et al [14] synthesized single-crystal SnO 2 nanowires for NO x gas sensors by vapor-liquid-solid (VLS) method and the use of SiO 2 /Si catalyst.…”
