"Developing New Organic Optoelectronic Devices For The Future
Light-Emitting Transistors, Organic Photo-detectors, and Lasers"
abstract : Organic semiconductors are very promising optoelectronic materials allowing
simple and low-cost fabrication of devices such as light-emitting diodes (OLED),
transistors, solar cells, sensors and lasers. I will discuss three aspects of our recent
progress in developing new optoelectronic devices using organic semiconductors. First, I
will show the design and fabrication of high performance light-emitting field effect
transistors (LEFET) – a relatively new device combining the emission properties of
OLED with the switching properties of a field effect transistor (FET) in a single device
structure. Second, I will cover our recent advances in developing organic semiconductor
lasers and possible electrically pumped organic lasers. Finally, I will demonstrate the
design and fabrication of ultra-sensitive visible organic photo-detectors. State-of-the-art
materials, design and device performance will be presented and discussed in this talk.
