Abstract

The objective of this course is to give insight into the device physics of organic (and related) light-emitting field-effect transistors, which are a new class of multifunctional devices that combine light-emission and switching properties in a single device. There are also interesting model systems to study charge transport and carrier recombination in a particular semiconductors. The attendees will be able to analyse the current-voltage-emission characteristics of various light-emitting FETs and assess current research papers in the field.

Course Content

  1. Refresher: Basics of charge transport, recombination and light emission in organic semiconductors
  2. Ambipolar charge transport in organic semiconductors and other materials (carbon nanotubes, low bandgap nanowires): preconditions, current-voltage characteristics
  3. Working principles and characterisation of ambipolar light-emitting FETs
  4. Single-layer polymer and organic single crystal light-emitting FETs
  5. Organic unipolar and multilayer light-emitting field-effect transistors
  6. Hybrid and carbon nanotube light-emitting FETs
  7. Potential applications and future directions

Biography of the lecturer:

Jana Zaumseil received her diploma in Physical Chemistry from the University of Leipzig in 2002. Following a one-year research internship at Bell Laboratories (Lucent Technologies, USA) she joined the Optoelectronics Group at the Cavendish Laboratory (University of Cambridge, UK) for her doctorate in physics supervised by Prof. Sirringhaus. There she developed the first ambipolar and light-emitting polymer field-effect transistors and received her Ph.D. in 2007. From 2007 to 2009 she held the Ugo Fano Postdoctoral Fellowship at the Center for Nanoscale Materials at Argonne National Laboratories (USA) where she studied light emission from carbon nanotubes. In 2009 she was appointed Professor for Nanoelectronics at the Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany. She received the prestigious Alfried-Krupp-Förderpreis in 2010 and a European Research Council Starting Grant in 2012. Her research focuses on optoelectronic devices based on novel nanomaterials with an emphasis on materials that emit and absorb light in the near-infrared such as carbon nanotubes.
