To overcome the limitations of lens aberrations in an electron microscope, Dr. Dennis Gabor invented electron holography, a technique that uses no lenses. The technique uses low energies (60-200eV), which makes it ideal for imaging fragile biological samples. To suspend samples, graphene has been...

Low energy electron point source (LEEPS) microscopy is the simplest embodiment of an electron microscope, consisting of only a source, a sample and a detector. In a specific regime, LEEPS may also be used to create in-line holograms; special interference patterns that contain the information...
