Cadmium sulfide polycrystalline thin films were grown on glass substrates by the chemical‐bath deposition technique (CBD) under application of both a pulsating direct electric and a dc magnetic field acting on the Cd‐ and S‐ions during growth in an aqueous solution which contains CdCl 2 and thiourea as source material for the cadmium and sulfur components, respectively. The field orientation in each case of deposition was chosen perpendicular as well as parallel to the growing CdS‐film interface. Two different values of the magnetic field strength were applied. Various properties of the films were studied, such as optical transmission and reflection, surface morphology, X‐ray diffraction, and dark electrical resistivity, as a function of the applied field configurations, which reveal a clear effect of the field presence during growth.
