The Atomic Structure of Quantum Dots,view and cross-sectional geometry. Important conclusions are drawn also on the growth processes during quantum dot formation as well as during overgrowth. It is demonstrated that uncapped InAs quantum dots on GaAs(001) have a pyramidal shape with dominating {137} side facets and—in the case of large

Special emphasis is put on the role of strain and piezoelectricity, where the latter is treated up to second order. Finally, we address the inverse problem of fitting spectroscopi

Phonons in Quantum Dots and Their Role in Exciton Dephasing,The change of the local elastic properties due to strain is calculated employing density functional theory and used as input for phonon calculations within continuum elasticity model. It is demonstrated that overall the exciton–phonon coupling strength is reduced, characteristic oscillations appear

Theory of the Optical Response of Singleand Coupled Semiconductor Quantum Dots,inement in less than three dimensions. In this chapter, the theory of both the linear optical properties and nonlinear dynamics of semiconductor quan- tum dots is discussed. The main focus is on the experimentally accessible quantities such as absorption/luminescence and pump-probe spectra. The resu
