“…On the other hand, the energy band-gap in ternary semiconductor alloys for Zn 1 − x Co x O as a function of alloy composition x is decreased when going from 0 to 1, whereas the ternary alloy of interest becomes a R→Г indirect band-gap structure once its x value becomes 0.25 and so over. We cite some references here [43][44][45][46] to compare with.…”

First-principles all electrons density-functional calculations for the band structure and magnetization of Zn 1 − x Co x O ternary magnetic alloys, in three phases namely zinc-blende, rocksalt and wurtzite have been reported. The computations are spin-polarized. An inspection of our electronic properties showed that the alloy system of interest exhibits a semiconducting character where the nature of the gap depends on the considered phase. An analysis of electronic charge density suggests that the bonding has a partially covalent character for ZnO which becomes weaker as far as the Co concentration increases. CoO is found to reach a total magnetization of 3 µ B per cell for zinc-blende and rocksalt phases and 6 µ B per cell for wurtzite phase.

Chemical spray pyrolysis (CSP) was utilized to create pure Zinc Sulfide (ZnS) and magnesium (Mg) doped thin films on a clean glass substrate at a temperature equal to 400°C. X-ray diffraction test revealed a cubic wurtzite crystal structure with average crystallite sizes of 10.99 and 12.27 nm for ZnS and ZnS: Mg, respectively. XRD analysis of the doped films revealed a polycrystalline structure with a predominant peak along the (220) plane and additional peaks along the (111), (200), and (222) planes. The grain size raised from 10.99 to 12.27 nm as a result of the XRD patterns. The increase in Mg content from 0% to 3%, affect the bandgap that fell from 3.52 to 3.42 eV. As the Mg content increased, the transmittance and refractive index of the films was lowered.

“…Therefore, the formed defects in CdO are helpful to refine the photoelectric properties [8]. By contrast [9], the approach of doping transition metal ions (TMs) has been proved the most potential one which is widely used to improve the electrical properties of CdO, as reported by NNJandow (lithium incorporation [10]), Ferekides (In‐doped [11]), Enzhu Li (Ga‐doped CdO thin films [2]), and Gupta et al (some rare earth element Gd‐doped [12]). Based on the above reports, it is expected that the conductivity of CdO can be competently modified by adding suitable metal dopants which may have smaller and/or equal ionic radii to that of host lattice atoms.…”

According to the high-order perturbation formulae of 3d 5 (Mn 2+ ) and 3d 9 (Cu 2+ ) ions in octahedron, the local structures and electron paramagnetic resonance (EPR) parameters ( g factors and hyperfine structure constants A) for Cu 2+ and Mn 2+ in CdO are theoretically studied in a consistent way. Due to the Jahn-Teller effect, both the substituted sites of Cu 2+ and Mn 2+ show the tetragonally elongated distortion with different elongation τ. Meanwhile, the crystal field and covalency around doped Cu 2+ and Mn 2+ are obtained, which can account for the electronic properties in doped CdO. In order to make further investigation of the potential optical and electrical properties, the band structure and density of states (DOS) of pure and transition metal ions (TMs) doped CdO are comparably calculated through density functional theory (DFT). The results show that the band gap of Mn 2+ -and Cu 2+ -doped CdO can be effectively reduced, due to the improved covalency between the central ions and ligand ions.
