Abstract :
Organic materials like oligophenyls, poly(para-phenylene) (PPP), and some derivatives (ladder polymers) are used as the active layer of light emitting diodes (LEDs). The electrical characteristics of these devices depend on the band structure of the organic layer as well as on the electrode materials. The optical and electrical LED performance is discussed with regard to the electronic structure of the stratified device arrangement.
