One-dimenstional nanostructures have been a main focus in various fields, such as electronics, photonics, and nanomechanics because they can provide high potential with their use. Although a large number of solution-based methods have been suggested and demonstrated to synthesize 1D nanostructures, anisotropic growhth of semiconductor 1D nanostrucures via solution process is not easy because  most solution-phase processes tend to limit the growth to zero-dimensional nanostructures in the form of spherical nanocrystallites or colloids. In this talk, we will provide synthetic routes to fabricate one-dimensional tellurium structure in aqueous and organic medium. Furthermore, the as-synthesized Te nanostructures can be a great template for the formation of various metal chalcogenide semiconductor (Ag2Te, CdTe, ZnTe, and PbTe) through cation exchange reaction. The final product transformed from the initial Te nanostructures keep their single crystallinity due to the small regime of reaction involved in this transformation.
