Abstract

Mercury sulfide (HgS) nanocrystalline thin films have been grown onto amorphous glass substrate by successive ionic layer adsorption and reaction (SILAR) trend at room temperature (27 °C). The optimized preparative parameters including ion concentration, number of immersion cycles, and pH of the solution are used for fine nanocrystalline film growth. A further study has been made for the structural, surface morphological, optical and electrical properties of the films by using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), optical absorption and dc two point probe method. The as-deposited grown HgS nanocrystalline films exhibited cubic phase, with optical band gap (Eg) of 2.0 eV and electrical resistivity of the order of 103 Ω cm. SEM and TEM images confirmed films of smooth surface morphology and nanocrystaline in nature with fine crystallites of 20–30 nm diameter, respectively.
