Abstract
AbstractThis chapter is concerned with a description of the main electromagnetic effects causing enhancement of optical absorption and optical emission in metal–semiconductor nanostructures. To this end, the chapter considers a pure electromagnetic mechanism, which relies on plasmon-induced enhancement of both local optical field intensity and density of photonic modes in the vicinity of a metal object. Relevant concepts are introduced and practical calculations of the electromagnetic enhancement in simplified model structures are presented. In particular, the classical electromagnetic problems are treated analytically for a plane metal–semiconductor interface and a metal sphere embedded into a semiconductor medium. The quasi-static approximation is employed to highlight the effects of the shape of the metallic object. The presented plots and diagrams, calculated within the analytical models, can be used to estimate the enhancement in real metal–semiconductor structures.
