Abstract
CdS films were grown onto glass substrates by the chemical-bath deposi tion (CBD) technique using cadmium chloride and thiourea as Cd and S i on suppliers, respectively. The growth process was carried out with an d without constant magnetic field applications. The field was applied perpendicular to the substrate at two values of the magnetic induction : 0.040 and 0.077 T. As result of the application of the magnetic fiel d during the growth process, changes in dark conductivity and carrier concentration were observed, added to the evolution of native defect e nergy levels, evidenced from van der Pauw and Hall effects versus temp erature data, and thermally stimulated current measurements, respectiv ely. In particular, the electrical properties of the CBD-CdS films bec ome enhanced by Geld application.
