“…[9,10] Some techniques such as electrode deposition, laser ablation, spray pyrolysis, radio frequency magnetron sputtering, close space vapor transport, and chemical bath deposition (CBD) can be employed to fabricate CdS and CdTe thin films. [11][12][13][14][15][16] The most simple and economical method of growing the CdS thin film is chemical bath deposition which can yield uniform and nearly stoichiometric CdS film at room temperature. CdS has some interesting properties.…”

The magnetic property in a material is induced by the unpaired electrons. This can occur due to defect states which can enhance the magnetic moment and the spin polarization. In this report, CdS and CdTe thin films are grown on FTO glass substrates by chemical bath deposition and close-spaced sublimation, respectively. The magnetic properties, which are introduced from oxygen states, are found in CdS and CdTe thin films. From the hysteresis loop of magnetic moment it is revealed that CdS and CdTe thin films have different kinds of magnetic moments at different temperatures. The M-H curves indicate that from 100 K to 350 K, CdS and CdTe thin films show paramagnetism and diamagnetism, respectively. A superparamagnetic or a weakly ferromagnetic response is found at 5 K. It is also observed from ZFC/FC curves that magnetic moments decrease with temperature increasing. Spin polarized density functional calculation for spin magnetic moment is also carried out.

“…Particularly, thin CdS films have attracted much attention for their desirable characteristics of high light transparency in the visible part of the solar spectrum, enhanced photoconductivity, and easy ohmic contact formation with other materials . Thin CdS films can be fabricated by different deposition techniques, such as chemical bath deposition , electrodeposition , laser ablation , radio frequency sputtering , spray pyrolysis , close space vapor transport , and vacuum evaporation . Device performance depends critically on the crystal quality of the CdS film when it is used as a buffer layer or a heterojunction n‐type partner with a p‐type material in a solar cell .…”

Resonant Raman scattering is highly desired for material study. It is experimentally not easy to reach the resonant scattering interaction between an incident photon and a material due to the limited available laser wavelengths. In this study, by employing silver plasmonic nanoparticles deposited on glass substrate and by in situ adjusting the cadmium sulfide (CdS) band gap through heat treatment, resonant Raman scattering condition (laser wavelength of 514.5 nm) was fully achieved in nanocrystalline CdS thin films. The dramatically enhanced Raman scattering allowed us to in situ monitor the phase transition that occurred during the heat treatment and to quantitatively characterize the fraction of the zincblende (cubic) CdS in the main base of wurtzite (hexagonal) CdS. Raman multi‐phonon and the corresponding high‐order scattering modes were observed due to the much enhanced surface nanoplasmonic electric field. Copyright © 2016 John Wiley & Sons, Ltd.

“…Since annealing brings positive as well as negative effects to CdS physical properties [7,8], therefore, a better understanding of the impact of the annealed CdS film on the properties of the CdS/CdTe solar cell is still needed. Polycrystalline CdS thin films have been prepared by different techniques including vacuum evaporation [9], chemical bath deposition (CBD) [10], electrodeposition [11], sputtering [12], and laser ablation [13].…”

Investigation of annealing temperature effect on magnetron sputtered cadmium sulfide thin film properties

Cadmium sulfide (CdS) thin films are deposited on the fluorine doped tin oxide coated glass substrate using the radio frequency magnetron sputtering setup. The effects of annealing in air on the structural, morphological, and optical properties of CdS thin film are studied. Optimal annealing temperature is investigated by annealing the CdS thin film at different annealing temperatures of 300, 400, and 500°C. Thin films of CdS are characterized by X-ray diffractometer analysis, field emission scanning electron microscopy, atomic force microscopy, UV-Vis-NIR spectrophotometer and four point probe. The as-grown CdS films are found to be polycrystalline in nature with a mixture of cubic and hexagonal phases. By increasing the annealing temperature to 500°C, CdS film showed cubic phase, indicating the phase transition of CdS. It is found from physical characterizations that the heat treatment in air increased the mean grain size, the transmission, and the surface roughness of the CdS thin film, which are desired to the application in solar cells as a window layer material.
