In order to optimize the growth conditions of strained-layer InGaAs QW high-performance lasers by MOVPE, different growth parameters are systematically varied. These test structures as well as complete laser structures are carefully analysed. Special

We report on time-resolved luminescence in GaAs quantum wells in high magnetic fields up to 21 T. Results on resonant tunneling and exciton relaxation including spin flip are presented

The influence of atomic hydrogen on the D-band photoluminescence in silicon is investigated. In contrast to other studies, a preferential passivation of the D1- and D4-band intensities but an increase in the intensities of the D2 and D3 bands after h

Excited singlet states of [Mo6Cl14]2− cluster anions, as previously predicted but undiscovered, are detected in single crystals of [N(C4H9)4]2Mo6Cl14 by means of photoluminescence measurements with time resolution in the picosecond regime. The inte

Monoatomic growth steps on vicinal (100) faces of gallium arsenide, grown epitaxially from gallium solution close to thermal equilibrium, are normally straight, equidistant and usually nucleated at dislocation emergence points. Beyond a critical temp

A hierarchy of logarithmically sequenced relaxation rates establishes a model for the "universal dielectric response", which is widely observed in condensed matter and displays a continually decelerated response in striking contrast to Debye relaxati

The recombination kinetics of the electron‐hole plasma in strongly excited, undoped Ga0.5In0.5P are investigated at 300 and 150 K by time‐resolved photoluminescence measurements using line‐shape analysis of transient spectra. Radiative recombin

A quasicolumnar structure of GaAs quantum wells with mean column diameters of d=1--10 \ensuremath{\mu}m is observed in narrow ${\mathrm{Al}}_{0.4}$${\mathrm{Ga}}_{0.6}$As/GaAs quantum wells prepared by liquid-phase epitaxy. The heterostructures are g
