| Article Name : | | Preparation and properties of chemically deposited PbS films from acidic and alkaline mediumnaltrexone information go vivitrol uk | | Author Name : | | | S. S. Karande | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-5613 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | The polycrystalline PbS thin films are prepared by chemical bath deposition technique in acidic and alkaline medium. Phase formation is investigated using X-ray diffraction technique. The electrical resistivity is calculated in the order of 102 ohm-cm in acidic medium and in alkaline medium is of the order of 101 ohm-cm. The activation energy in acidic medium is 0.422 eV and in alkaline medium is 0.258 eV. Photoconductivity, thermoelectric power, optical properties, IR spectra in acidic as well as in alkaline medium are studied. | | Keywords : | | - terminological differences,
