Injection-tuning at metal-semiconductor interfaces to boost organic electronics — •Florian von Wrochem1 and Maria Anita Rampi2 — 1Materials Science Laboratory, Sony Europe, Stuttgart (Germany) — 2Universita di Ferrara, Ferrara (Italy)
The driving force in molecular electronics within the past decades has been to shift organic-based thin-film devices from basic research to the application level. In this talk, a few strategies toward the realization of organic electronic devices on the basis of ultrathin functional organic layers are outlined, specifically by leveraging on the self-assembly process at interfaces. In the first place, we show how large area molecular junctions of outstanding robustness can be realized using densely packed molecular metal-terpyridine complex oligomers, which might enable a versatile platform for functional optoelectronic layers. In the second part, a new class of self-assembled monolayers exhibiting a pronounced intrinsic dipole moment is presented, by which the injection properties in organic semiconductors can be tuned in view of in solar cell and organic memory applications.
