Charge transport

Seminar on Organic Electronics
In this lecture the concept of charge carrier trapping is discussed. The electron and hole current in a variety of conjugated polymers is shown to be limited by universal traps. [mehr]

OLED

Seminar on Organic Electronics
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. [mehr]

OPV

Seminar on Organic Electronics
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. [mehr]

OPV

Seminar on Organic Electronics
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. [mehr]

OFET

Seminar on Organic Electronics
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). [mehr]

OFET

Seminar on Organic Electronics
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. [mehr]

Ferroelectrics

Seminar on Organic Electronics

Organic Memories

Seminar on Organic Electronics
This lecture will introduce the concept of memory and information storage, with a general overview of different memory devices. Then the ferroelectric memory devices and their physics are explained, discussing the concepts of volatile and non-volatile memories as well as the (dis)advantages of ferroelectric memories. [mehr]

Org. Bioelectronics

Seminar on Organic Electronics
The lecture on organic bioelectronics, we will cover the following topics: Introduction to bioelectronics, OTFT-based biosensors, device functionalization, device architectures (electrolyte-gated transistors, dual gate transistors, electrochemical transistors), soft, stretchable materials and devices, biodegradable and edible electronics .In addition to their ability to conduct electronic charges, organic materials also support ionic transport. These materials are also known as mixed conductors. In the second part of the lecture module, the basic concepts of organic mixed conductors will be discussed as well device operation and their application for biosensing. In addition to their ability to conduct electronic charges, organic materials also support ionic transport. These materials are also known as mixed conductors.
