CathodoluminescenceSemiconductor Spectroscopy and Devices
Cathodoluminescence (CL) is the emission of light from a material under excitation by a high energy electron beam (or "cathode ray"). Various materials emit CL including many minerals and semiconductors. In semiconductor physics analysis of the emitted light can be used as a characterisation tool in order to probe among other things 1
