Quan Niu：Degradation Mechanism and Device Physics of Printable Organic Light-Emitting Diodes

Quan Niu have joined the State Key Laboratory of Luminescent Materials and Devices, South China University of Technology as a Professor/Principal Investigator. She is currently a guest researcher at the Max-Planck-Institute for Polymer Research, Germany. Quan obtained her PhD (in Chemistry) from the Max-Planck-Institute for Polymer Research, Germany and master degree from Technical University of Munich, Germany. Her doctoral and master supervisors include renowned scientist in semiconductor device physics, Prof. Paul W. M. Blom (Director of Max-Planck-Institute for Polymer Research), and Prof. Wolfgang Bruetting (Director of 4th Institute for Physics, University of Augsburg). Her recent work led to a breakthrough in understanding the degradation mechanism of organic light-emitting didoes (OLEDs), and at the first time demonstrated stable polymer light-emitting diodes, which is the key technology to realize low cost large scale light-emitting devices, and therefore booting the commercialization of printable and plastic displays. With special emphasis on device stability and degradation mechanism, her research has been published on leading scientific journals such as Nature Materials and Physical Review Letters. She has also been authorized 5 US patents and 10 Chinese patents. One of her works, which exploit the negative capacitance phenomena to non-destructively characterize the trap density in organic semiconductors, has been featured in highlights in Physical Review Letters.

Degradation Mechanism and Device Physics of Printable Organic Light-Emitting Diodes

Polymer light-emitting diodes (PLEDs) are promising for large–area, low–cost printable displays. However, the limited stability of PLEDs under current stress impedes their commercialization. In spite of large efforts over the last two decades, a fundamental understanding of the degradation mechanisms has not been accomplished. In this course, we will give detailed introduction on degradation mechanism and device physics of printable organic light emitting diodes, which could include: charge transport and recombination in organic semiconductors, OLED device and printable displays, degradation mechanism and origin of negative capacitance in organic diodes.
