Control of spontaneous and stimulated emission in conjugated polymers

Conjugated polymers now provide a class of processible, film-forming semiconductors and metals. We have worked on the development of the semiconductor physics of these materials by using them as the active components in a range of semiconductor devices. In particular, we showed that these polymers could be used as the emissive layers in thin-film light-emitting diodes (LEDs), with improvement in device performance through control of chemical structure and by use of heterostructure device architectures.
