Cathodoluminescence (CL) is the emission of photons as the result of the interaction between energetic electrons and matter. In semiconductors, the excitation by a highly energetic electron beam generates electron-hole (e-h) pairs within a specimen volume. The excess carriers then thermalize and diffuse inside the material and finally recombine, either by nonradiative processes or by photon emission.....

Abstract
Cathodoluminescence (CL) is the emission of photons as the result of the interaction between energetic electrons and matter. In semiconductors, the excitation by a highly energetic electron beam generates electron-hole (e-h) pairs within a specimen volume. The excess carriers then thermalize and diffuse inside the material and finally recombine, either by nonradiative processes or by photon emission.....File in questo prodotto:
