In this project we will explore ion transport in conjugated polymers. Research during this project was centered on subsequent topics: 1. Driving mechanisms (migration and diffusion) for ion transport. 2. Relationship between ions, charge, and volume change. 3. Link between experimental situations
Organic electronics is a rapidly evolving field with large number of applications having high possibility of commercial success. Even though a great progress has been created, many organic electronic applications: organic light-emitting diodes (OLEDs), organic field effect transistors (OFETs), organic solar cells,
Label-free detection of DNA has been successfully demonstrated on field effect transistor (FET) based devices. Since conducting organic materials was discovered and have attracted more and more research efforts by their profound advantages, this work will focus on utilizing an organic field effect transistor (OFET) as DNA sensor.
In this thesis we explore in particular the dynamics of a special type of quasi-particle in pi-conjugated materials termed polaron, the origin of which is intimately related to the strong interactions between the electronic and the vibrational degrees of freedom within these systems.
Conjugated polymers have been found useful in a wide range of applications such as solar cells, sensor elements and printed electronics, due to their optical and electronic properties. Functionalization with charged side chains has enabled water solubility, resulting in an enhanced interaction
