Modification of the properties of chemically deposited CdS thin films grown under magnetic field and variable growing parameters

Characterization of chemical bath deposited CdS thin films at different deposition temperature

“…Other authors report this effect as well [22][23][24][25]. Using the standard expression for direct transition between two parabolic bands (˛h ) 2 = A(h − Eg), the optical band gap Eg of CdS thin films has been calculated by extrapolating the linear (˛h ) 2 vs. h plots to (˛h ) 2 = 0, as shown in Fig.…”

“…In the CBD process, the influence of the deposition parameters on film formation, particularly the role of deposition temperature on the film structure and properties, is extremely critical. It has been reported that increase of deposition temperature can accelerate the film growth [21], lower the band gap [22][23][24][25], increase conductivity [22], and improve the crystallinity [4,25] by various groups. However, the comprehensive study on the influence of deposition temperature on film physical properties was very few.…”

Recent status of chemical bath deposited metal chalcogenide and metal oxide thin films

“…The CdS thin films deposited under constant magnetic field showed low resistivity and high band gap energy value compared to samples grown without magnetic field [38]. Lejmi and Savadogo [39] deposited CdS thin films using heteropolyacids or phosphotungstic acid and found that the deposited CdS films have a mixed structure (45% hexagonal and 55% cubic) with a predominance of the cubic phase for long growth periods.…”

The influence of external magnetic field on the structural and optical properties of nanocrystalline ZnO thin films prepared by dip coating method

“…Nevertheless, J. Vidal et al [34] claimed "grains have approximately the same size and shape as those grown without MF". O. Vigil [66] reported that there is a decrease in the crystallite size, when the samples are grown under a magnetic field. Still there is a need for further studies in order to fully understand this phenomenon.…”
