title = "Excitons and Excitonic Effects During Optical Transitions",
abstract = "In this chapter, excitons and excitonic effects during optical transitions are discussed. The transition energy for 1D, 2D, and 3D materials which include the exciton binding energy provide a focal point for the chapter. The well-known Elliott description of optical absorption for 3D, 2D, and 1D materials and the Sommerfeld factor for Coulomb enhancement are discussed. The effect of quantum confinement is described. A quantum mechanical derivation of excitonic effects on direct gap optical transitions which alters the energy dependence of optical absorption and thus the dielectric function is presented. Photoluminescence spectra from semiconductors and quantum wells are also presented.",
