The SEM1 images depict nanostructured boron-doped diamond (BDD) electrodes grown on boron-doped silicon pillars. In this collaborative effort Si pillars were fabricated at the MESAplus facilities at University of Twente. Subsequently BDD growth has been performed at Condias. The high-quality sp3 carbon BDD electrodes exhibit excellent stability and activity for organic electrosynthesis reactions as shown by Talal Ashraf (PhD student at UTwente).
1A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.
