We present analytical results which describe the properties of the exciton ground state in a single semiconductor quantum dot (QD). Calculations are performed within the Luttinger–Kohn and Bir–Pikus Hamiltonian theory. We show in an explicit form

We report measurements of dynamic (a.c.) electrical conductivity in borosilicate glasses doped with cadmium sulfoselenide and copper and silver iodides in a wide temperature range below the glass transition temperature T g and at different frequencie

The phonon-induced flip of the exciton spin in single flat semiconductor quantum dots with a light-hole exciton ground state is studied. The corresponding quartet, split by the exchange interaction, consists of three bright states and a dark state lo

In weakly confining quantum structures such as interfacial islands or quantum disks the exciton-spin relaxation is governed by two independent electron and hole spin flip processes between the optically active and dark states. A microscopic theory fo

We report on the injection of electron spins into InGaAs quantum dots with an efficiency of up to 60%. This injection is observed in p-i-n light-emitting diode structures using the diluted magnetic semiconductor ZnMnSe as spin aligner (spin-LED). The

We study the relaxation of the exciton spin (longitudinal spin–relaxation time T1) in single asymmetrical quantum dots (QD) at low temperatures. The main relaxation mechanism is due to the exciton spin–acoustic phonon coupling via the strain–de

In a differential absorption experiment the induced infrared transitions from the excitonic 1s to the 2p levels in Cu 2 O have been investigated. Intermediate densities of 1s excitons were created by cw-laser excitation while the interexcitonic 1s to
