title = "Coulomb effects in optically excited semiconductor quantum dots",
abstract = "The linear and nonlinear optical properties of semiconductor microcrystallites are analyzed taking into account the Coulomb interaction between the carriers and the influence of surface charges. A numerical matrix diagonalization method is used to evaluate the energy eigenvalues and the corresponding eigenstates. It is predicted that excited two-pair states lead to a pronounced induced absorption on the high energy side of the one-pair resonance. This prediction is confirmed by femtosecond and nanosecond experiments in CdSe and CdS quantum dots. Additionally, effects of traps or impurities and external dc electric fields are discussed.",
