Abstract:

Most polymers, or plastics we see and use everyday are insulators. A special class of polymers, however, can have electrical conductivity similar to a metal or emit light when an electrical current is passed through and therefore can be the active material of many useful devices. My research as a condensed matter and device physicist involves fabricating and studying novel polymer light-emitting devices which promise to have many advantages over existing electroluminescent technologies. Recently at Queen's we have demonstrated world’s largest polymer light-emitting devices. A great amount of information can be obtained about the physics involved in these devices by direct imaging using only a digital camera. In this talk I will share with you some of the most beautiful images and movies out of more than 30,000 pictures we have taken so far. I will show you sometimes the most effective and convincing technique used in research is also the simplest and the most elegant. Graduate research can certainly be both rewarding and fun.

Refreshments will be available after the talk in our lounge, Rm 207.
