PbTe Nanorods by Sonoelectrochemistry

摘要

Size,shape,and compositional control are at the heart of nanochemistry.Herein,we present a novel method that allows control over all three variables in a simple one-step,wet-chemical procedure. One-dimensional(ID)nanomateri-als are of great interest for the construction of high-performance thermoelectric(TE)devices. Theoretical calculations indicate that improvement in TE efficiency can be achieved as the diameter of the ID structures approaches a few nanometers.
