Dieter Bimberg,Marius Grundmann,Frank Heinrichsdorff,Nikolai N. Ledentsov,Victor M. Ustinov,A. E. Zhukov,A. R. Kovsh,Mikhail V. Maximov,Y.M. Shernyakov,B. V. Volovik,A. F. Tsatsul’nikov,P. S. Kop’ev,Zh. I. Alferov +12 more
TL;DR: In this article, the authors used the concept of electronically-coupled quantum dots (QDs) and oxide-defined 10 μm apertures for surface-emitting QD lasers (300 K).
Journal ArticleDOI
Radiative states in type-II GaSb/GaAs quantum wells.
Nikolai N. Ledentsov,J. Böhrer,M. Beer,Frank Heinrichsdorff,Marius Grundmann,Dieter Bimberg,Stefan Ivanov,B. Ya. Meltser,S.V. Shaposhnikov,I. N. Yassievich,N. N. Faleev,P. S. Kop’ev,Zh. I. Alferov +12 more
TL;DR: Intense luminescence from staggered band line-up GaSb-GaAs heterostructures up to room temperature is demonstrated and a bimolecular recombination mechanism is revealed in PL and in time-resolved PL studies.
Journal ArticleDOI
