Recent theoretical and experimental studies of semiconductor quantum dots are summarized. The one and two electron hole‐pair states are investigated and the effects of quantum confinement and Coulomb interaction are discussed. Besides intrinsic quantum dots, also the effects of trapped carriers and surface polarizations are analyzed. The nonlinear properties are studied by computing the pump‐induced absorption changes (differential transmission spectra). Good agreement with nanosecond and femtosecond hole‐burning experiments is found.
