Abstract: In the
preparation of Bismuth Telluride thin films are reported in the present work.
Measurements of the structural and optical properties of Bi2Te3thin
films were studied by X-ray diffraction, transmission (TEM) and scanning (SEM)
electron microscope and electron diffraction techniques. Bi2Te3 thin
films were "polycrystalline" Hexagonal form. The crystallite size was determine .The
optical energy gap was evaluated. The study was carried out under vacuum.,These
properties has been reported to date. It was found from the optical properties
studies that the type of transitionof Bi2Te3 is
an indirect transition.
