On artefact-free reconstruction of low-energy (30-250 eV) electron holograms
Tatiana Latychevskaia, Jean-Nicolas Longchamp, Conrad Escher +1
Low-energy electrons (30-250 eV) have been successfully employed for imaging individual biomolecules. The most simple and elegant design of a low-energy electron microscope for ima…
Low-energy electron holographic imaging of gold nanorods supported by ultraclean graphene
Jean-Nicolas Longchamp, Conrad Escher, Tatiana Latychevskaia +1
An ideal support for electron microscopy shall be as thin as possible and interact as little as possible with the primary electrons. Since graphene is atomically thin and made up o…
Pulsed Electron Holography
Matthias Germann, Tatiana Latychevskaia, Conrad Escher +1
A technique of pulsed low-energy electron holography is introduced that allows for recording highly resolved holograms within reduced exposure times. Therefore, stacks of holograms…
Coherent diffraction and holographic imaging of individual biomolecules using low-energy electrons
Tatiana Latychevskaia, Jean-Nicolas Longchamp, Conrad Escher +1
Modern microscopy techniques are aimed at imaging an individual molecule at atomic resolution. Here we show that low-energy electrons with kinetic energies of 50-250 eV offer a pos…
Graphene Unit Cell Imaging by Holographic Coherent Diffraction
Jean-Nicolas Longchamp, Tatiana Latychevskaia, Conrad Escher +1
We have imaged a freestanding graphene sheet of 210 nm in diameter with 2 Angstrom resolution by combining coherent diffraction and holography with low-energy electrons. The entire…
Coherent microscopy at resolution beyond diffraction limit using post-experimental data extrapolation
Tatiana Latychevskaia, Hans-Werner Fink
Conventional microscopic records represent intensity distributions whereby local sample information is mapped onto local information at the detector. In coherent microscopy, the su…
