Structure to property relationships: From molecules to organic electronic devices
Dr. Karin Zojer
TU Graz, Institute of Solid State Physics
17:15 - 18:15 Tuesday 25 October 2016 TUG P2 The field of organic electronics is continuously fueled by the promise of using organic chemistry to craft molecules tailor-made for a desired application. I will discuss my contributions to establish such structure-to-property relationships and “design rules” in highly diverse applications, be them for molecules or for entire devices considering their full complexity.
I will demonstrate that owing to the peculiar properties of organic semiconductors, there is rich, unique, and partially ignored physics taking place in organic devices.[1,2] In particular, I will show by means of organic solar cells [1] and organic transistors,[2] that the device performance is critically or even solely determined by effects confined to interfaces.
Inspired by the discussion of device applications, I will briefly present my ideas on how to pave the way to establish a better grasp on disordered, organic materials in the future.
