Photonic Processes Visualized with Electrons in Photoemission Electron Microscopy (PEEM)

Photoemission electron microscopy (PEEM) combines in a unique way light and electron optics: As photo-emitted electrons are used in the imaging process, light-optical phenomena can be imaged with a resolution significantly below the light-optical diffraction limit. In addition the light-optical excitation offers non-destructive operation conditions, an inherent sensitivity to the surface-near region and extremely short observation times [1].
