Influence of post annealing on CBD deposited ZnS thin films

Effect of Chemical Bath Deposition Variables on the Properties of Zinc Sulfide Thin Films: A Review

“…Research [ 101 , 128 , 129 ] discovered that the effect on ZnS films resulted in a change in optical properties but had no effect on the crystalline structure (either amorphous or crystalline film on film deposition). Oliva et al [ 128 ] synthesized CBD-ZnS films by annealing the films at 200 °C and 400 °C.…”

“…Annealing effect uniforms the ZnS thin film surface, reduces defect density and lowers transmittance. Khalil et al [ 129 ] investigated CBD ZnS thin film post-annealing at 100–400 °C in air during 1 h. All deposited and annealed films exhibited crystalline structures. There was no impurity discovered other than ZnS, which matched the hexagonal structure of wurtzite.…”

“…All the CBD parameters, when combined, can cause several effects on the films, which are sometimes difficult to regulate and recognize, resulting in inconsistent findings across researchers. Due to the repeatability of the stated procedure, it was necessary to apply the CBD technique to obtain high-quality ZnS films [ 129 ]. All researchers who want successful outcomes should consider the above aspects ( Section 3.4.1 , Section 3.4.2 , Section 3.4.3 , Section 3.4.4 , Section 3.4.5 , Section 3.4.6 , Section 3.4.7 , Section 3.4.8 and Section 3.4.9 ) that might affect results.…”
