Coherent properties of a tunable low energy electron matter wave source
Andreas Pooch, Michael Seidling, Nicole Kerker +5
A general challenge in various quantum experiments and applications is to develop suitable sources for coherent particles. In particular, recent progress in microscopy, interferome…
Three-dimensional surface topography of graphene by divergent beam electron diffraction
Tatiana Latychevskaia, Wei-Hao Hsu, Wei-Tse Chang +2
There is only a handful of scanning techniques that can provide surface topography at nanometre resolution. At the same time, there are no methods that are capable of non-invasive…
Vibrational dephasing in matter-wave interferometers
Alexander Rembold, Georg Schütz, Robin Röpke +4
Matter-wave interferometry is a highly sensitive tool to measure small perturbations in a quantum system. This property allows the creation of precision sensors for dephasing mecha…
Low-voltage coherent electron imaging based on a single-atom electron
Wei-Tse Chang, Chun-Yueh Lin, Wei-Hao Hsu +4
It has been a general trend to develop low-voltage electron microscopes due to their high imaging contrast of the sample and low radiation damage. Atom-resolved transmission electr…
Electron matter wave interferences at high vacuum pressures
Georg Schütz, Alexander Rembold, Andreas Pooch +2
The ability to trap and guide coherent electrons is gaining importance in fundamental as well as in applied physics. In this regard novel quantum devices are currently developed th…
Biprism Electron Interferometry with a Single Atom Tip Source
Georg Schütz, Alexander Rembold, Andreas Pooch +7
Experiments with electron or ion matter waves require a coherent, monochromatic and long-term stable source with high brightness. These requirements are best fulfilled by single at…
Correction of dephasing oscillations in matter wave interferometry
Alexander Rembold, Georg Schütz, Wei-Tse Chang +5
Vibrations, electromagnetic oscillations and temperature drifts are among the main reasons for dephasing in matter-wave interferometry. Sophisticated interferometry experiments, e.…
