Sažetak
Lead-sulfide (PbS) films have been deposited by chemical deposition method on glass substrates. The details of the preparation method are described. The advantage of this method is simple, relatively inexpensive and easily controlled method that is producing large-area films. Some data about the electrical properties, structure, composition of the films and thermal stability of the powder samples are also presented. The structure and crystallite sizes were determined by X-ray diffraction studies. The films are very adherent to the substrates. The films are polycrystalline and average crystallite sizes are 15 nm. The surface morphology of the as-deposited and heated films was studied with a scanning electron microscope. The rate of deposition and terminal thickness have been determined. Hall measurements were performed at room temperature for films deposited on glass substrate to determine the carrier density, Hall mobility and the mean free path of the carriers.
