Keywords:chalcogenide, nano-needle, composition analysis

We have investigated nano-structure of chalcogenide which has been studied as memory and thermoelectro materials. In this presentation, we report that size and composition for nano-structure created from Bi₂Te₃ thin film by simple annealing technique.
