Excitonic lifetimes in thin In x Ga 1-x As/InP quantum wells
TL;DR: In this paper, the radiative excitonic lifetime in very thin quantum wells is studied as a function of the well width, and the authors explain the dependence of the lifetime on well width by a reduced transition probability caused by the penetration of the envelope wave function of electrons into the barrier material.

Carrier capture in intermixed quantum wires with sharp lateral confinement
TL;DR: In this paper, the authors fabricated GaAs/GaAlAs quantum wires with widths between 220 and 40 nm by high-dose (2×1014 cm−2) Ga implantation in a locally masked single quantum well structure.

Optical properties of wire and dot structures for photonic applications
Heinz Schweizer,G. Lehr,F. E. Prins,G. Mayer,E. Lach,R. Krüger,E. M. Fröhlich,M.H. Pilkuhn,G. W. Smith +8 more
TL;DR: In this paper, the realization and physical investigation of wire and dot structures was reported and fabrication requirements for low dimensional semiconductor structures were discussed for masked implantation enhanced intermixing technique (MIEI) and for dry etching technique with subsequent overgrowth.

G. Mayer,F. E. Prins,G. Lehr,Heinz Schweizer,H. Leier,B. E. Maile,J. Straka,Alfred Forchel,G. Weimann +8 more
TL;DR: Time-resolved investigations on the photoluminescence of GaAs/Al x Ga 1-x As quantum wires indicate a reduction of the energy relaxation in quasi-one-dimensional (1D) systems.

Time resolved spectroscopy on etched GaAs/GaAlAs-quantum-microstructures
TL;DR: In this paper, the authors investigated the recombination luminescence of the charge carriers in time-resolved spectroscopy as a function of the wire width and found that a strong reduction of the recombinations lifetime and a corresponding quenching of the luminecence intensity with decreasing wire width.
