High-performance devices using organic semiconductors

Abstract:
Synthetic control over the molecular constituents of organic semiconductors allows unprecedented control over their aggregate solid-state properties. Band-gap-like and band-edge-like properties can be tuned, seemingly at will (through the sweat and toil of brilliant synthetic chemists). This power comes, however, with a Faustian bargain. In contrast to inorganic semiconductors where atoms fully concede their individuality to collective quantum states, resulting in charge-carrier mobilities measuring in the hundreds to over a thousand square centimeters per volt second (cm2/VĚs), the molecular individuality retained in organic semiconductors leads to localization and mobilities typically amounting to less than 3cm2/VĚs. That creates a problem for applications requiring appreciable currents such as, for example, organic LEDs (OLEDs).
