Transmission Electron Microscopy Studies along the Process Chain of Printable Electronics based on Nanoparticulate Systems — •Stefanie Spallek, Benjamin Butz, and Erdmann Spiecker — Center for Nanoanalysis and Electron Microscopy (CENEM), Department of Materials Science, University of Erlangen-Nuremberg, Germany

Printable electronics based on nanoparticulate systems is a highly active research field due to its enormous economical potential. The goal is to develop routes for fabrication of electronic and optoelectronic devices on flexible substrates by cheap and scalable printing techniques that use inks (or pastes) containing conducting or semiconducting nanoparticles. The performance of the final device critically depends on each step of the process chain which comprises synthesis of the nanoparticles, their functionalization and dispersion to printing pastes, the fabrication of the devices and possible after-treatments. The structural properties that influence the device performance include the shape and size distribution of the nanoparticles after synthesis, their 3D arrangement and interconnection in the functional layers as well as defects that may be introduced at various steps of the fabrication. In this contribution we show several examples of TEM studies along the process chain of printable electronic devices as well as the challenges of the corresponding sample preparation.
