| Popis: | In the present work, copper zinc sulphide (CuZnS2) thin films with and without complexing agents using glass plate as substrate were prepared. Chemical bath deposition method was employed to deposit the thin films. Powder X-ray diffraction (PXRD) patterns of the prepared films indicate the crystalline nature of CuZnS2 with cubic phases. The SEM and AFM images illustrate that the deposited films were highly influenced on the polyhedral morphology by the complexing agents. The influence of complexing agents on absorbance and band gap of the CuZnS2 thin films were characterized using UV-Vis absorption studies. Hall effect measurements indicate the CuZnS2 thin film without surfactant belongs to p-type semiconductor and become n-type after adding the complexing agents EDTA and Leishman stain. From the I-V curve, all the samples having slow conducting nature was found for changing the voltage with the current from -32 nA to +30 nA using solar stimulator. |
