Fine structure of excited excitonic states in quantum disks
M. M. Glazov, E. L. Ivchenko, R. v. Baltz +1
We report on a theoretical study of the fine structure of excited excitonic levels in semiconductor quantum disks. A particular attention is paid to the effect of electron-hole lon…
Exciton spin relaxation in single semiconductor quantum dots
E. Tsitsishvili, R. v. Baltz, H. Kalt
We study the relaxation of the exciton spin (longitudinal relaxation time ) in single asymmetrical quantum dots due to an interplay of the short--range exchange interaction…
Temperature dependence of polarization relaxation in semiconductor quantum dots
E. Tsitsishvili, R. v. Baltz, H. Kalt
The decay time of the linear polarization degree of the luminescence in strongly confined semiconductor quantum dots with asymmetrical shape is calculated in the frame of second-or…
Frequency Dependent Conductivity of the Fibonacci-Chain
Dieter Walther, Ralph v. Baltz
A real-space renormalization method for the frequency dependent conductivity of the periodic approximants of the Fibonacci chain is developed. This scheme is based on the known 2x2…
Optical absorption in semiconductor quantum dots: Nonlocal effects
F. Thiele, Ch. Fuchs, R. v. Baltz
The optical absorption of a single spherical semiconductor quantum dot in an electrical field is studied taking into account the nonlocal coupling between the field of the light an…
Optical properties of quantum wires: Disorder-scattering in the Lloyd-model
Christian Fuchs, Ralph v. Baltz
The Lloyd model is extended to the exciton problem in quasi one-dimensional structures to study the interplay between the Coulomb attraction and disorder scattering. Within this mo…
