In-situ Fabrication of Bi2Te3-Te Sheet-rods Using Te Nanowires as Template

doi:10.3724/SP.J.1077.2010.00664

Abstract

Abstract: One-dimensional semiconductor materials Bi₂Te₃-Te nanocomposites, with a sheet-rod nanostructure can be fabrication on a large scale using Te nanowires as the in-situ template under a simple reflux process, and the yield is high up to 90%. The product was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscope (EDS) and transmission electron microscope (TEM). It is a promising way to fabricate one-dimensional nanocrystals of other metals and semiconductors. The influence of KOH, EDTA and reaction time are discussed. The formation mechanism of such a heterostructure is also proposed.

Key words: nanowires, reflux process, Bi₂Te₃-Te, template synthesis
