Te/PEDOT:PSS nanowires

The information provided here is intended to complement work that has already been published by providing details that we have found helpful. This page is in no way intended to replace on-the-job training. Be sure to read all Safety Data Sheets and understand the hazards of this type of chemistry before proceeding.

Use(s) of Material

This is an extremely robust synthetic technique that can be tuned to produce nanowires with lengths ranging from 100-500nm. Due to the highly conductive shell of PEDOT:PSS ligand coating the Te nanowires, these materials have generated interest for applications in hybrid thermoelectrics devices.
