Band Offset in (Ga,In)As/Ga(As,Sb) Heterostructures
S. Gies, M. J. Weseloh, C. Fuchs +5
A series of (Ga,In)As/GaAs/Ga(As,Sb) multi-quantum well heterostructures is analyzed using temperature- and power-dependent photoluminescence (PL) spectroscopy. Pronounced PL varia…
Excitonic terahertz absorption in semiconductors with effective-mass anisotropies
P. Springer, S. W. Koch, M. Kira
A microscopic approach is developed to compute the excitonic properties and the corresponding terahertz response for semiconductors characterized by anisotropic effective masses. T…
Magnetic control of Coulomb scattering and terahertz transitions among excitons
J. Bhattacharyya, S. Zybell, F. Eßer +9
Time-resolved terahertz quenching studies of the magnetoexcitonic photoluminescence from GaAs/AlGaAs quantum wells are performed. A microscopic theory is developed to analyze the e…
Pair-excitation energetics of highly correlated many-body states
M. Mootz, M. Kira, S. W. Koch
A microscopic approach is developed to determine the excitation energetics of highly correlated quasi-particles in optically excited semiconductors based entirely on a pair-correla…
Systematic investigation of THz-induced excitonic Rabi splitting
M. Teich, M. Wagner, D. Stehr +8
Weak near-infrared and strong terahertz excitation are applied to study excitonic Rabi splitting in (GaIn)As/GaAs quantum wells. Pronounced anticrossing behavior of the split peaks…
Extraction of many-body configurations from nonlinear absorption in semiconductor quantum wells
R. P. Smith, J. K. Wahlstrand, A. C. Funk +6
Detailed electronic many-body configurations are extracted from quantitatively measured timeresolved nonlinear absorption spectra of resonantly excited GaAs quantum wells. The micr…
Optically induced coherent intra-band dynamics in disordered semiconductors
C. Schlichenmaier, I. Varga, T. Meier +2
On the basis of a tight-binding model for a strongly disordered semiconductor with correlated conduction- and valence band disorder a new coherent dynamical intra-band effect is an…
Propagation of Coulomb-correlated electron-hole pairs in semiconductors with correlated and anticorrelated disorder
P. Thomas, I. Varga, T. Lemm +4
Local ultrafast optical excitation of electron-hole pairs in disordered semiconductors provides the possibility to observe experimentally interaction-assisted propagation of correl…
Interaction-assisted propagation of Coulomb-correlated electron-hole pairs in disordered semiconductors
D. Brinkmann, J. E. Golub, S. W. Koch +3
A two-band model of a disordered semiconductor is used to analyze dynamical interaction induced weakening of localization in a system that is accessible to experimental verificatio…
Optical absorption of strongly correlated half-filled Mott-Hubbard chains
F. Gebhard, K. Bott, M. Scheidler +2
In this last of three articles on the optical absorption of electrons in a half-filled Peierls-distorted chain we address the dimerized extended Hubbard model in the limit of a lar…
