Imaging the potential distribution of individual charged impurities on graphene by low-energy electron holography
Tatiana Latychevskaia, Flavio Wicki, Conrad Escher +1
While imaging individual atoms can routinely be achieved in high resolution transmission electron microscopy, visualizing the potential distribution of individually charged adsorba…
Mapping Unoccupied Electronic States of Freestanding Graphene by Angle-Resolved Low-Energy Electron Transmission
Flavio Wicki, Jean-Nicolas Longchamp, Tatiana Latychevskaia +2
We report angle-resolved electron transmission measurements through freestanding graphene sheets in the energy range of 18 to 30 eV above the Fermi level. The measurements are carr…
Direct observation of individual charges and their dynamics on graphene by low-energy electron holography
Tatiana Latychevskaia, Flavio Wicki, Jean-Nicolas Longchamp +2
Visualizing individual charges confined to molecules and observing their dynamics with high spatial resolution is a challenge for advancing various fields in science, ranging from…
Design and Implementation of a Micron-Sized Electron Column Fabricated by Focused Ion Beam Milling
Flavio Wicki, Jean-Nicolas Longchamp, Conrad Escher +1
We have designed, fabricated and tested a micron-sized electron column with an overall length of about 700 microns comprising two electron lenses; a micro-lens with a minimal bore…
