The course gives an overview of the field of organic electronics. This involves fundamental processes as charge and energy transport in organic semiconductors, as well as their synthesis and characterization and finally their application in various devices as organic LEDs, solar cells, transistors and biosensors.
1. Introduction to the course
General introduction to the field of organic electronics.
2. Electronic properties of Conjugated Polymers
in this lecture the electronic structure of conjugated polymers is discussed. It is explained why conjugated polymers are semiconductors and not metals. The concepts of polarons and energetic disorder are discussed. Both lead to the formation of localized states and thermally activated (hopping) conduction.
3. Charge transport in organic semiconductors 1
In this lecture the concept of space-charge limited current is demonstrated and applied to hole transport in conjugated polymers. The density and field dependence of the hole mobility is discussed.
4. Charge transport in organic semiconductors 2
In this lecture the concept of charge carrier trapping is discussed. The electron in a variety of conjugated polymers is shown to be limited by a universal trap.
5+6. Theory of charge transport
Simulations of charge transport in organic thin films using Kinetic Monte Carlo simulations is discussed
7. Photophysics of Organic Semiconductors
This lecture will cover the fundamentals of light-matter interaction in organic semiconductors, focusing on mechanisms that are relevant to organic electronics.
8. Optical Characterization Techniques for Organic Electronics
This lecture will provide an overview of steady-state and time-resolved optical experiments, and what the results from these measurements can teach us about our devices.
9. OFET 1
This course presents in-depth discussion and analysis of metal-oxide-semiconductor field effect transistors (MOSFETs). History of development of MOSFETs, device structure, device types and modes of operation will be discussed as a part of introduction to the organic thin films transistors (OTFT).
10. OFET 2
In this module on organic transistors (OTFT), we will cover the following topics: role of components (dielectric and semiconductor) on device parameters, interfaces (metal/semiconductor and semiconductor/dielectric), charge carrier transport: uni- vs ambipolar. Organic transistors as potential candidate for flexible electronic.
11+12 Perovskite FET
In this lecture the fabrication and operation of transistors based on 2D perovskites will be discussed
13 Device physics of organic light-emitting diodes 1: charge injection, transport, and recombination
In this lecture, the device physics of organic light-emitting diodes is treated. It is demonstrated how an organic light-emitting diodes works. The mechanisms of injection, transport and recombination of charges in organic light-emitting diodes are described. It is shown how the drift and diffusion current in a device can give information of charge transport and recombination. Furthermore, the impact of charge trapping and trap-assisted recombination on the efficiency of organic light-emitting diodes is treated. It is explained how the efficiency of these devices can be improved by the use of specialized materials and device layouts, eliminating exciton quenching and charge trapping.
14. Device physics of organic light-emitting diodes 2: charge injection, transport, and recombination
15. Device physics of organic solar cells 1: photocurrent generation
In this lecture, the device physics of organic solar cells is treated.
First, the operating mechanism of an organic photovoltaic device is described. The generation of free charges is discussed and the influence of charge transport and recombination on the extracted photocurrent is described.
16. Device physics of organic solar cells 2: nongeminate recombination
In this lecture, the recombination of photogenerated charge carriers is discussed. Generated electrons and holes can be lost through recombination processes. The rate of free-carrier recombination is discussed. It is also shown that recombination can occur via trap states. It is explained how such a process can be identified and the impact on the photovoltaic characteristics and device efficiency is discussed.
17. Organic ferroelectrics
The first half of the lecture will introduce insulator, piezoelectrics and ferroelectrics. The second half of the lecture will discuss physical characteristics of different ferroelectric polymers. The students are expected to learn what a ferroelectrics are and what is the origin of ferroelectricity in organic materials.
18. Organic memories
The first half of the lecture will introduce the concept of memory and information storage, with a general over view of the memory candidates. The second half of the lecture will have a focus on ferroelectric memory devices and their physics. The students are expected to learn the concept of volatile and non-volatile memories as well as the (dis)advantages of ferroelectric memories.
20. Organic Bioelectronics I - Applications of OFETs In this lecture applications of OFETs in flexible electronics will be discussed. We will look into prerequisites for portable electronics such as low voltage operation as well as transistor architectures and functionalization strategies for biosensing applications.
21. Organic Bioelectronics II - Mixed Conductors In addition to their ability to conduct electronic charges, organic materials also support ionic transport. These materials are also known as mixed conductors. In this lecture, the basic concepts of organic mixed conductors will be presented as well as device operation principles of OECTs (organic electrochemical transistors).
22. Organic Bioelectronics III – Stretchable and green electronics This lecture will focus on material and device aspects for wearable and on-skin electronics including flexible and stretchable electronic materials and device-to-tissue interfaces. Further aspects will span towards green electronics and biodegradable materials.
23. + 24 Polymer Physics
All or part of the following concepts and topics will be treated: the physics of single polymer chains (freely jointed, freely rotating, wormlike), random walk models, polymer chains in solution, swelling, collapse, excluded volume theory, Flory theory, theta solvent, ideal vs real chains, dilute, semi-dilute, concentrated regimes, polymer dynamics and viscoelasticity.
25+26. Chiral optoelectronics
The concept of chirality will be discussed and its realization in supramolecular structures/ The second part will discuss possible applications of chiral structures.
27 + 28 Solution Processing
All or part of the following concepts and topics will be treated: evaporation, condensation, film-formation liquid-liquid phase separation, polymer diffusion, free energy of mixing, Flory-Huggins theory, Cahn-Hilliard-de Gennes theory, link between polymer film micromorphology and device operation.
29+30. Characterization
This lecture on polymer characterization provides basic knowledge about physico-chemical characterization methods on micro- and mesoscopic length scales. A broad variety of methods characterizing thermal behavior, molecular structure and weight as well as morphology and meso structures are discussed. Particular analytical challenges common to polymers such as broad distributions of entities, memory phenomena and heterogeneous morphologies are emphasized and state of the art solutions to these challenges are presented.
