“…2, we notice that the intensity of peak (111) increases slightly after doping, which could be attributed to the dopant incorporations into the CdO matrix of our obtained films. This behavior has been, already, observed in literature [8,20]. The average crystallites size of the films was calculated using the Scherrer formula [21].…”

“…CdO is a group II-VI transparent conductor with a direct bandgap of 2.3−2.7eV and an n-type conductivity with crystallites that are simple cubic crystal systems with an Fm-3m space group and a lattice constant of 4.67 Å [7]. Furthermore, a relatively low electrical resistivity of 10 −3 to 10 −4 Ωcm was used in many optoelectronic applications such as transparent conducting oxides, solar cells, smart windows, optical communications, flat-panel displays, phototransistors, and other types of applications such as IR heat mirrors, gas sensors [8,9,10].…”

TM (TM = Sn, Al) doped and co-doped CdO thin films were deposited by spray pyrolysis technique on glass substrate at temperature 350 ˚C. The effect of TM doping and co-doping on the structural, morphological, optical, and electrical properties of CdO thin films was investigated. The obtained films are crystallized in the cubic structure and oriented along the preferential (111) crystallographic plane. The average optical transmittance reaches 79% in the visible range for Sn doped CdO films and 74% for Al-Sn co-doped films. The gap values of the obtained samples are between 2.29 and 2.49 eV. All the deposited films exhibit n-type conductivity with a low electrical resistivity of 7.85.10-4 Ω.cm obtained for Al doped CdO films.

Solvent volume dominated improved Haacke’s quality factor values realized for CdO:Mo thin films well suited for optoelectronic applications

Solvent volume has profound influence on the structural, morphological and optoelectronic properties of spray deposited thin films. In this work solvent volume (20, 30, 40, 50 and 60 mL) impact on the optoelectronic properties of spray deposited molybdenum doped cadmium oxide (CdO:Mo) has been reported. XRD reveals cubic crystal structure of the CdO:Mo thin films. Crystallite size increases with solvent volume up to 50 mL and for the 60 mL it decreases. SEM images show cauliflower shaped grains. EDX spectra revealed Cd, Mo and O in all the films. Thickness dominated the UV-Vis-NIR properties of the films. The increased band gap values with increased solvent volume are attributed to the Burstein-Moss effect. The 50 mL solvent volume coated film exhibited increased transparency, low sheet resistance (21.6 Ω/□), low resistivity (0.93 × 10 -3 Ω-cm) and high figure of merit value (1.15 × 10 -2 Ω −1 ). Fabrication of a photodiode with p-Si/n-CdO:Mo/Ag heterostructures is done to study its photo response behaviour.

“…One of the significant transparent conducting oxide nanomaterials is cadmium oxide (CdO). Additionally, CdO nanoparticles have a significant impact on a variety of applications, including gas sensors, heat mirrors, phototransistors, solar cells, and thin-film resistors [1][2][3][4][5][6]. Researchers have used a variety of methods to deposit pure CdO and doped CdO films on various substrates; Renu Kumari et al [7] used the sol-gel-derived screen-printing process to deposit gadolinium-doped CdO film.…”

Pure films of cadmium oxide and indium-doped cadmium oxide films were deposited using a spray pyrolysis technique. The deposited films were structurally characterised using the X-ray diffraction method. The structural studies revealed that films are polycrystalline in nature with a cubic lattice. The decrease in particle size from 42 nm to 34 nm was observed as dopant was introduced. For pure CdO thin films, the band gap energy obtained was of the order of 2.58 eV, and it decreased to 2.32 eV with the addition of dopant.
