Study quantum effects using cathodoluminescence

Quantum mechanical effects are ubiquitous in physics and materials science.  Often such effects are related to quantum confinement where one or more dimensions of a material are reduced to a size similar to the electron/hole wave functions as is the case in quantum wells/discs/dots, 2D materials, and emitter centers for example. This provides unique possibilities and tunability (e. g. in dispersion, spectral output), beyond conventional bulk materials. CL imaging provides unique possibilities to study the optical properties of such systems at the nanoscale.

Additionally, the (quantum) interaction with light and fast electrons in an electron beam can be used to enhance electron microscopy, for example through photo-induced near-field microscopy (PINEM). In general, such developments are connected to efficient light injection/extraction similar to what is used for cathodoluminescence imaging.
