N2 - CdS thin films were grown by chemical bath deposition (CBD) method on glass substrates under a constant magnetic field, at different deposition temperatures and thiourea concentrations. The optical, electrical and structural evolution as a function of the above mentioned parameters were characterized. A combination of deposition temperature and thiourea concentration was obtained with optimal result, i.e., that which produces the highest band-gap energy (BGE) and the smallest resistivity under the magnetic field. On the basis of the optical and structural characterization, we found that in the evolution of BGE, quantum confinements effects are present.
