Cathodoluminescence (CL) is a technique where radiation is emitted from a material after being excited by an electron beam. CL imaging shows light intensity across a sample, while CL spectroscopy analyzes the light's wavelength or energy. This method reveals crucial information about the material’s electronic properties, structural defects, and chemical composition. It is widely used for semiconductor research, optoelectronics, and material analysis in devices like microLEDs, transistors, and solar cells.
