Optical Properties and Radiative Processes

Abstract

In this chapter, we deal with the optical properties of nanostructures. In a first part, we start with a general formulation of the optical transition probabilities taking into account specific problems related to the small size of the systems. In a second part, we consider the electron—phonon coupling using macroscopic or microscopic formulations and we analyze its consequences on the optical line-shape. The last two sections are devoted to the description of the optical properties in nanostructures of semiconductors with direct or indirect bandgap.
