The aim of this chapter is to present a simple but general band structure picture of the metal-semiconductor interface and compare that with the characteristics of the metal-conjugated polymer interface. The discussion is focused on the polymer light emitting diode (LED) for which the metal-polymer contacts play a central role in the performance of the device. The metal-polymer interface also applies to other polymer electronic devices that have been fabricated, e.g., the thin-film field-effect transistor3, but the role of the metal-polymer interface is much less cruical in this case and... 

Electroluminescence from Jt-conjugated polymers was first reported in 1990 by Burroughes et al. [1], Compared to inorganic materials and small molecules, polymers promise easy fabrication of large-area displays and illumination devices. In fact, the first flexible polymer light-emitting diode (LED) was demonstrated by Gustafsson et al. in 1992 [2].
