Growth and structural properties of indium sesquitelluride (In2Te3) thin films (original) (raw)

Indium sesquitelluride (In 2 Te 3 ) compound was synthesized by mixing and melting the pure individual elements in stoichiometric proportions. The synthesized compound was utilized for the deposition of In 2 Te 3 thin films on glass and freshly cleaved NaCl substrates using flash evaporation technique. The structure of In 2 Te 3 thin films has been studied on the glass substrates by X-ray diffraction technique and on the cleavage faces of NaCl by electron diffraction technique. It was observed that the deposition from an ordered ␣-phase compound results in polycrystalline films on glass substrate at 473 K which are predominant ␣-phase and random ␤-phase compounds resulting in single crystal films on NaCl substrate at 523 K. Effect of source and substrate temperature on the composition of In 2 Te 3 was also studied.
