A chemical method has been developed for the preparation of mercury selenide (HgSe) thin films on a glass substrate at room temperature. Mercury selenide thin films were prepared by using mercury formamide, a novel complex compound, and sodium selenosulphate as a selenide releasing agent. The adherence and uniformity of the film were improved by adding polyvinyl pyrrolidone as a minor additive. X-ray diffraction, optical absorption and electrical measurements were performed to characterize the deposition of mercury selenide. The films were found to be amorphous, p-type semiconductors with an energy gap of 1.42eV.
