Author(s): UM Jadhav and MS Shinde
Abstract: Nano crystalline semiconducting Ag2S films have been prepared onto corning glass substrates using chemical bath deposition (CBD) and modified chemical bath deposition (M-CBD) methods. In chemical bath deposition (CBD), preparative parameters such as concentration, deposition time, complexing agent and pH of the bath are optimized, while in modified chemical bath deposition (M-CBD) preparative parameters such as concentration, immersion cycles, immersion time and rinsing time were optimized. The comparative Physical properties study of CBD and MCBD deposited is carried out. The deposited films were characterized by different characterization techniques to study structural, surface morphological, optical and electrical properties. Comparative. The structural studies show that, the formation of Ag2S thin films with an average crystallite size of 25.61 nm by CBD and 21 nm by MCBD. Optical studies show a direct band gap 1.78 eV by CBD and 2.09 by MCBD. The room temperature electrical resistivity is of Ag2S thin films is 1.4 x 105 Ω-cm for CBD and 2.76 x 105 Ω-cm M-CBD method. The films exhibit electrical conductivity as seen by thermo-emf measurements indicating that Ag2S is n-type semiconductors.
