21_20/2009Organic Semiconductors: Relating the Functional Properties of an Organic Semiconductor to Molecular Structure by nc-AFM (Adv. Mater. 20/2009)

The influence of the molecular scale arrangement on the optoelectronic properties of organic semiconductors can be investigated using noncontact AFM to determine the local structure of molecular islands and probe the local optical excitation response of different molecular-scale structures, report Peter Grutter and co-workers on p. 2029. The cover image shows a 3D rendering of a high-resolution noncontact AFM image of a monolayer of PTCDA molecules trapped in a nanoscale pit in NaCl, one of the structures investigated, under “illumination”.
