HL 28: Focus: Exploitation of Anisotropy in Organic Semiconductors I (joint session CPP/HL)
Tuesday, March 17, 2020, 10:00–12:30, ZEU 222
Molecular glasses and semi-crystalline thin films play a key role in organic semiconductor devices, particularly organic light-emitting diodes and solar cells. Surprisingly, some of these materials exhibit considerable anisotropies regarding their molecular orientation which leads to non-isotropic electronic properties. In spite of the importance for optoelectronic devices, however, this phenomenon is not fully understood yet. This focus session will bring together concepts from the physics of glasses, structure formation in soft matter as well as applications of such anisotropic molecular solids in organic electronics.
Organized by: Wolfgang Brütting (University Augsburg), Sebastian Reineke (TU Dresden); Wolfgang Wenzel (Karlsruher Institut für Technologie).
