What is it about?

This work is about charge transport and conduction mechanism in organic semiconductors, particularly in PEDOT (poly(3,4-ethylenedioxythiophene), one of the most popular conducting polymers. High conductivity with good optical transparency and stability are some of the salient features of PEDOT; also, its moderate band gap and low redox potential have made PEDOT an interesting system to explore new properties and applications. These materials are considered a promising alternative to conventional inorganic semiconductors. Semiconducting polymers are π-conjugated systems, and their understanding has not yet been achieved as concrete as ordered and crystalline systems such as inorganic semiconductors. Organic semiconductors, particularly polymers, are much more mechanically robust and lighter than inorganic semiconductors. This work is an attempt to improve the understanding of such systems.

Why is it important?

Our findings provide a novel approach to studying the conduction mechanism in conducting polymers in the Triangle approach. It is vital to understand conducting polymers since these are complex systems. This methodology of studying such a system will be pretty interesting and helpful.


This article is part of my Ph.D. work, revealing and opening a new way to analyze semiconducting systems. It was part of great learning.
