Multiple Exciton Generation in Semiconductor Quantum Dots.
Multiple exciton generation in quantum dots (QDs) has been intensively studied as a way to enhance solar energy conversion by utilizing the excess energy in the absorbed photons. Among other useful properties, quantum confinement can both increase Coulomb interactions that drive the MEG process and decrease the electron-phonon coupling that cools hot excitons in bulk semiconductors. However, va...
متن کاملNonlinear optical response and exciton dephasing in quantum dots
The full time-dependent four-wave mixing polarization in quantum dots is microscopically calculated, taking into account acoustic phonon-assisted transitions between different exciton states of the dot. It is shown that quite different dephasing times of higher exciton states in pancake anisotropic InGaAs quantum dots are responsible for the experimentally observed [1] double-exponential decay ...
متن کاملDiamagnetic response of exciton complexes in semiconductor quantum dots.
We report measurements of diamagnetic shifts for different exciton complexes confined in small InAs quantum dots. The measured diamagnetic responses are sensitive to the number of carriers in the exciton complexes, with systematic differences between neutral excitons, biexcitons, and trions. Theoretical calculations suggest that such systematic differences arise from very different extents of e...
متن کاملStark effect on the exciton complexes of individual quantum dots
The emission spectrum of exciton complexes formed in individual self-assembled quantum dots (QDs) embedded into a p-n junction is theoretically studied using an effective mass model. We calculate the particle Coulomb interactions, eletronhole overlaps and transition energies of exciton complexes for the different strength and direction of electric field. Both redshifts and blueshifts are observ...
متن کاملResonant photon-exciton interaction in semiconductor quantum dots
Semiconductor self-assembled quantum dots form a three dimensional confinement for charge carriers in the solid state matrix. The confinement modifies the density of states, leading to atom like optical properties of quantum dots that can be studied by absorption or emission of photons. Due to the sharp resonance lines that are observed in optical spectra, quantum dots are often referred to as ...
