Organic-Assisted Nano-Sized Antimony Telluride Prepared by Co-Precipitation Reductive Route

Abstract

Nano-sized antimony telluride is of much interest for improving the thermoelectric figure of merit. In the present work, organic-assisted antimony telluride nanorods were successfully fabricated by a simple hydrothermal method. The products were characterized by means of X-ray diffraction, scanning electron microscope, and transmission electron microscope. The results show that the typical antimony telluride synthesized by co-precipitation reductive route is rodlike in shape with about 35 nm in thickness and 300 nm in edge length.

Single‐Source Precursor‐Based Deposition of Sb2Te3 Films by MOCVD**

“…Bulk Sb 2 Te 3 finds widespread technical applications in minipower‐generation systems and micro‐coolers, charge coupled device (CCD) technology, and infrared detectors . Since nanostructuring is expected to further enhance the figure of merit due to reduction of the thermal conductivity, Sb 2 Te 3 films and nanostructures with well‐defined morphologies have been fabricated both via solution phase and gas phase processes such as solvothermal processes, microwave heating, vapor transport growth, vapor‐liquid‐solid growth, electrochemical atomic layer epitaxy, electrochemical deposition, DC and RF sputtering, and molecular beam epitaxy (MBE) processes . In addition, MOCVD using trialkylstibanes SbR 3 (R = Me, Et) and dialkyltellanes TeR′ 2 (R = Et, i Pr) have been successfully employed …”

Considering the effect of a ligand as new complexing agent in the characteristics of TiO2 nanoparticles

“…Surely, not each molecule is an equally good ligand. Fundamentally, ligands that accomplish the task of adsorbent and stabilizer have a functional head group and one or more hydrocarbon large groups, and both elements perform a role in the control of nucleation and growth [13][14][15][16][17][18][19][20][21].…”
