Biography

Since my first contact with organic electronics, back in 2006 at the TuGraz, I have always been intrigued by the challenges and opportunities this rich class of materials offer. I started to work on poly(triphenylamines), amorphous and semiconducting polymers, which turned out to be electrically stable under ambient conditions. Order is crucial for efficient charge transport, and that’s why I moved on to single crystal devices to gain information about correlation between crystal structure and electrical performance. I learned that depending on molecular structure and chemical composition, electrical properties can be tuned from semiconductors all the way to organic metals. In this context, tetrathiafulvalene derivatives are an appealing class of materials. Pure single crystals are challenging to process, but combining processing conditions of polymers with the electrical properties of single crystalline materials in composites allow appealing applications (Google Scholar).
