Cathodoluminescence Microscopy of Nanostructures on Transparent Substrates

Cathodoluminescence (CL), the excitation of light by an electron beam, has gained attention as an analysis tool for investigating the optical response of a structure, at a resolution that approaches that in electron microscopy, in the nanometer range. However, the application possibilities are limited because the use of transparent substrates,...

Low-energy electron beams through ultra-thin foils, applications for electron microscopy

This thesis has discussed two electron microscopy applications that make use of ultra-thin foils: the tunnel junction emitter and the low-energy foil corrector. Both applications have in common that the electron beam is sent through the thin foil at low energy. Part of the electrons will scatter in the foil, thus causing a reduction of the...
