Subject | Influence of molecular ordering and orientation in organic electromic devices. |
In contrast to their inorganic counterparts, the majority of molecular
semiconductors exhibit an additional degree of freedom due to their anisotropic shape, namely molecular orientation. This has a profound impact on the growth behaviour and thus the degree of order found in thin films with consequences for charge carrier transport and as well as for optical properties.
This talk will present different aspects of the influence of molecular ordering and orientation in various types of devices and discuss the consequences for their functioning. Examples are
-the growth of highly crystalline molecular semiconductors for ambipolar field-effect transistors
-the interplay between crystallinity and efficiency in organic photovoltaic cells
-the influence of the emitter orientation on light-extraction efficiency in organic light-emitting diodes
-the impact of partially oriented polar molecules at organic semiconductor hetero-interfaces.
