Journal ArticleDOI
Photoreflectance, photoluminescence, and microphotoluminescence study of optical transitions between delocalized and localized states in GaN 0.02 As 0.98 , Ga 0.95 In 0.05 N 0.02 As 0.98 , and GaN 0.02 As 0.90 Sb 0.08 layers

TL;DR: In this paper, a broadening of optical transitions in as-grown and annealed GaN, GaN 0.95 and GaN0.08 alloys were studied with photoreflectance (PR), photoluminescence (PL), and microphotoluminecence (\ensuremath{\mu}PL) in a broad range of temperatures.
Journal ArticleDOI
Single photon emission at 1.55 μm from charged and neutral exciton confined in a single quantum dash
Ł. Dusanowski,Marcin Syperek,Paweł Mrowiński,W. Rudno-Rudziński,Jan Misiewicz,Andre Somers,Sven Höfling,Martin Kamp,J.P. Reithmaier,G. Sęk +9 more
TL;DR: In this paper, charged and neutral exciton complexes confined in a single self-assembled InAs/InGaAlAs/inP quantum dash emitting at 1.55 µm were investigated by measuring high-spatial-resolution polarization-resolved photoluminescence and cross-correlations of photon emission statistics.
Journal ArticleDOI
Photoreflectance evidence of multiple band gaps in dilute GaInNAs layers lattice-matched to GaAs
R. Kudrawiec,E.-M. Pavelescu,J. Wagner,G. Sęk,Jan Misiewicz,M. Dumitrescu,Janne Konttinen,A. Gheorghiu,M. Pessa +8 more
TL;DR: In this article, photoreflectance measurements on lattice-matched dilute GaInNAs-on-GaAs layers with low indium and nitrogen content are reported, which give evidence that these layers also exhibit several distinct band gaps.
Journal ArticleDOI
Localized and delocalized states in GaNAs studied by microphotoluminescence and photoreflectance
TL;DR: In this article, the light-hole transition in photoreflectance spectrum has been investigated with microphotoluminescence (μ-PL) spectra and the authors attributed the recombination of localized excitons trapped at local potential minima.
Journal ArticleDOI
Interband transitions inGaN0.02As0.98−xSbx∕GaAs(0<x⩽0.11)single quantum wells studied by contactless electroreflectance spectroscopy
Robert Kudrawiec,Marta Gladysiewicz,Jan Misiewicz,Homan Yuen,Seth R. Bank,Mark A. Wistey,Hopil Bae,James S. Harris +7 more
TL;DR: In this article, contactless electroreflectance (CER) features related to ground and excited state transitions have been observed and compared with those obtained from theoretical calculations, which were performed in the framework of the effective mass formalism model.
