“…These values then correspond to an almost complete separation of the doublet. The factor 2 increase of the 1s exciton oscillator strength, associated with an equal increase of the exciton binding energy, is consistent with the theoretical value obtained with a simple variational description of the exciton wave function [13].…”

“…Also in nanostructured materials, e.g. in semiconductor quantum dots (QDs), numerous electron-phonon scattering effects have been reported that modify the excitation [12,13] or relaxation [14][15][16][17][18][19] properties of thermally or optically excited electronic states, i.e. intraband excitations or excitons.…”

Recently, highly-accurate multi-configuration time-dependent Hartree (MCTDH) electron dynamics calculations demonstrated the efficient long-range energy transfer inter-Coulombic decay (ICD) process to happen in charged semiconductor quantum dot (QD) pairs. ICD is initiated by intraband photoexcitation of one of the QDs and leads to electron emission from the other within a duration of about 150 ps. On the same time scale electronically excited states are reported to relax due to the coupling of electrons to acoustic phonons. Likewise, phonons promote ionization. Here, the QDs' acoustic breathing mode is implemented in a frozen-phonon approach. A detailed comparison of the phonon effects on electron relaxation and emission as well as on the full ICD process is presented, which supports the previous empirical finding of ICD being the dominant decay channel in paired QDs. In addition the relative importance of phonon-phonon, phonon-electron, and electron-electron interaction is analysed.

The interband multi-photon absorption spectrum from a semiconductor superlattice induced by an intense optical wave in the presence of uniform magnetic and electric fields is analysed theoretically. The oscillating electric field of the optical wave and the uniform electric and magnetic fields are all directed perpendicular to the heteroplanes. The explicit dependences of the coefficient of the multi-photon absorption on the frequency and magnitude of the oscillating electric field, on the superlattice parameters and on the magnitudes of the uniform electric and magnetic fields are obtained. The uniform electric field is assumed to be sufficiently strong to provide Wannier-Stark localization of the carriers. The electron-hole cyclotron frequency and the frequency of the Stark oscillations are taken to be commensurate with their ratio being rational. It is shown that, under these conditions and in contrast to onephoton spectra, an enhancement of the series of resonances could arise. It is also shown that the form of the spectrum depends on the relationship between the cyclotron and Stark frequencies and on the number of photons involved.
