Lead Selenide (PbSe) thin film of 5765 A thickness had been deposited by thermal evaporation in vacuum system and characterised in Physics Laboratories at FMIPA UI Depok. Optical characterisation is done with spectrophotometer MR. Using the Hishikawa method, applied in a computer program, will yield optical parameters such as index of refraction (n), extinction coefficient (k), absorption coefficient (a) and energy gap (Eg). Electrical characterisation is done by measuring the conductivity toward the temperature between ...

Lead selenide thin films were prepared by chemical bath deposition method using aqueous of lead nitrate, sodium selenate and sodium tartrate. The influence of bath temperature towards the properties of the thin films was studied. The films were characterized by X-ray diffraction, scanning electron microscopy and UV-Vis spectrophotometer. The XRD results confirmed the polycrystalline cubic structure of PbSe films. The intensity of major peak at 2Θ= 25.1° which belonged to (111) plane of PbSe, increased ...
