Abstract

We report the observation of fringes from a three grating electron interferometer. Interference fringes have been observed at low energies ranging from 6 keV to 10 keV. Contrasts of up to 25% are recorded and exceed the maximal contrast of the classical equivalent, Moire deflectometer. This type of interferometer could serve as a separate beam Mach-Zehnder interferometer for low energy electron interferometry experiments.
