Organic semiconductors as candidates for advanced optoelectronic devices

Organic semiconductors are gaining an increasing attention due to their promise of novel optoelectronic devices. The main attraction of these materials stems from their potential integration with flexible materials, which would result in ultrathin flexible multicolor displays. Basic electronic properties of typical representatives of organic semiconductors are reviewed. The operation of a light-emitting device based on organic semiconductors is fundamentally different from its inorganic counterparts due to differences in electronic transport properties. The crucial component apart from the active material is represented by the metal-organic semiconductor contacts.
