Abstract
The growth of AgI (silver iodide) thin films has been performed in aqueous medium using simple chemical method at room temperature (25 °C). Silver nitrate and potassium iodide have been used as source materials. Thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), surface photovoltage (SPV) and optical absorption spectroscopy. Glass and indium doped tin oxide (ITO) coated glass was used as substrates. The thin films were surface homogeneous with mixed β and γ-phases with surface roughness value of 21 nm. Optical transmission on glass exceeds 80% for 150 nm thick film with the direct band gap value of 2.85 eV. The change in crystal phases after transition temperature is studied by SPV measurements.
