Lecture

Organic Materials: Charge Delocalization & Disorder

Description

This lecture covers the intermolecular charge delocalization in organic materials, discussing the effects of dynamic and static disorder on charge carriers in solid-state crystals and polymers. It also explores the behavior of crystalline organic materials at high charge carrier densities and the impact of disorder on polaron bands. The instructor explains the formation of extended polaron defect states in highly disordered systems and the changes in energy levels at crystalline/amorphous interfaces, highlighting the active transport regions in p-type and n-type organic semiconductors.
