Numerous studies on Cu-doped ZnO (CZO) thin film doped as a p-type material have been reported due to its applications in optoelectronic and gas sensing devices. The synthesis and fabrication of CZO thin films by various techniques have been reported, but the sol-gel technique for both spin and dip coating has attracted much attention due to its sa...
Article
Nanoparticles (NPs) synthesized by the co-precipitation technique show many attractive properties such as small particle size, high crystallinity, high average pore diameter and high specific surface area. However, numerous reports show that some characteristics of the Ni-doped ZnO (NZO) NPs remain controversial such as optical bandgap (Eg), surfac...
Article
Some efforts have been made on Cu-doped ZnO (CZO) structures to study the electronic, structural, magnetic and optical properties from first-principles calculations by different computer codes. This is very interesting to review in detail about CZO structures. A summary of the convergence criteria of geometry optimization for CZO structures from th...
Article
The materials properties of quaternary diamond-like Li2CaGeO4 have been studied. The computations are used through the full-potential linearized augmented plane wave method within the local orbitals and ultra-soft pseudo-potentials. Calculated structural parameters are found to be accordant with those of experiment. The elastic anisotropy of the cr...

Pure and copper-doped zinc oxide thin films at different contents x (Zn1-xCuxO; 0≤x ≤ 0.125) were synthesized by sol–gel spin coating process and investigated using various techniques. All samples exhibited a polycrystalline with wurtzite hexagonal phase, which wasn't altered and getting relaxed by Cu-doping. The grain size increased and changed it...
Article
In this study, the thickness effect of 4% Mn‐doped ZnO thin films on structural, optical, and morphological properties is investigated. The films are deposited on a glass substrate using the sol‐gel spin coating method. Phase analysis indicates that all films have a hexagonal wurtzite structure with a high preferential c‐axis orientation. All struc...

The current study investigates the effect of thickness on the structural, morphological, electronic, and optical properties of pure zinc oxide (ZnO) and 7% Mn-doped ZnO thin films, deposited by sol–gel spin coating method. All films exhibited a hexagonal wurtzite structure with a high preferential c-axis orientation. The surface morphology showed a...

... It possesses the ability to achieve uniform CZO nanostructures, even at low temperatures under controlled conditions. Transition metals doped ZnO thin films have been studied with various defects such as manganese (Mn) [24][25][26] , silver (Ag) [8] , aluminum (Al) [10] , antimony (Sb) [16] , cobalt (Co) [20] , sodium (Na) [22] , bismuth (Bi) [27] and copper (Cu) [3] . Among them, Cu is extensively used to enhance the properties of the ZnO host lattice [ 2 , 9 , 28-38 ] such as transparency [ 28 , 39 ], ferromagnetism [ 40 , 41 ], crystalline quality and conductivity [42] . ...
... In addition to these advantages, the fabrication of TCO using low cost and simple methods such as the sol-gel process have attracted increasing attention from many researchers to explore the effects of the preparation conditions on the properties of the resultant CZO thin films [14][15][16][17][18][19][20][21][22] . There are many factors influencing the growth mode of the CZO thin films as well as their physicochemical properties. ...
... The attributes of a film are usually influenced by conditions of preparation like the method of deposition, temperature of post deposition annealing, and different kinds of substrate. This has already been reported that the opto -electronic characteristics of sol-gel ZnO film are mainly affected by the film thickness [20][21][22]. The thickness could be varied by varying the coatings as well as by the concentration of solution in a sol-gel film. ...
