Principles of electron wave front modulation with two miniature electron mirrors

We have analyzed the possibilities of wave front shaping with miniature patterned electron mirrors through the WKB approximation. Based on this, we propose a microscopy scheme that uses two miniature electron mirrors on an auxiliary optical axis that is in parallel with the microscope axis. A design for this microscopy scheme is presented for...

Electron wave front modulation with patterned mirrors

We propose a microscopy scheme for the controlled modulation of the electron wave front that utilizes patterned electron mirrors. The ability to control the wave front of the electron finds many applications in electron microscopy, for instance in contrast enhancement techniques, beam mode conversion, low-dose imaging techniques such as quantum...

Electrostatic electron mirror in SEM for simultaneous imaging of top and bottom surfaces of a sample

The use of electron mirrors in aberration correction and surface-sensitive microscopy techniques such as low-energy electron microscopy has been established. However, in this work, by implementing an easy to construct, fully electrostatic electron mirror system under a sample in a conventional scanning electron microscope (SEM), we present a...

Flat electron mirror

Electron beams can be reflected by an electrode that is at a more negative potential than the cathode from which the beam is emitted. We want to design a mirror with a flat mirror electrode where the electrons are reflected at a plane very close to the electrode. The wave front of an electron can then be shaped when the mirror contains a...
