Light Emission by Tunneling Electrons, Fluorescence, and Raman Scattering in a Multilayer Geometry

Abstract

We review the use of electromagnetic Green's functions for multilayered geometries in the analysis of several experiments. These experiments include fluorescence and Raman scattering from surface adsorbed molecules, and light emission by tunneling electrons in the metal-insulator-metal (MIM) tunnel junction and the scanning tunneling microscope (STM). The Green's function approach is extremely useful when several interfaces with roughness are involved.
