Prof. Karl Leo, director of the Institute of Applied Physics at TU Dresden is a semiconductor physicist at heart. His main interests are novel semiconductor systems such as semiconducting organic thin films, with a special focus on understanding fundamental device principles and their optical response.
He has been fascinated by organic light-emitting diodes (OLEDs) since seeing his first one in 1991. It was a polymer OLED and it had a lifetime of a few minutes, Leo says. To see how it went from those few minutes to products like today s television screens was a wonderful development.
