Journal ArticleDOI
Terahertz Light-Matter Interaction beyond Unity Coupling Strength.
Andreas Bayer,Marcel Pozimski,Simon Schambeck,Dieter Schuh,Rupert Huber,Dominique Bougeard,Christoph Lange +6 more
TL;DR: This work introduces a paradigm change in the design of light-matter coupling by treating the electronic and the photonic components of the system as an entity instead of optimizing them separately and pushes ΩR/ωc of cyclotron resonances ultrastrongly coupled to metamaterials far beyond unity.
Journal ArticleDOI
Identification of nnp and npp Auger recombination as significant contributor to the efficiency droop in (GaIn)N quantum wells by visualization of hot carriers in photoluminescence
Manfred Binder,Anna Nirschl,Roland Zeisel,Thomas Hager,Hans-Juergen Lugauer,Matthias Sabathil,Dominique Bougeard,Joachim Wagner,Bastian Galler +8 more
TL;DR: In this article, the authors report the direct observation of hot carriers generated by Auger recombination via photoluminescence spectroscopy on tailored (AlGaIn)N multiple quantum well (QW) structures containing alternating green and ultra-violet (UV) emitting (GaIn),N QWs.
Journal ArticleDOI
Clustering in a precipitate-free GeMn magnetic semiconductor
TL;DR: The first study relating structural parameters of precipitate-free Ge0.95Mn0.05 films to magnetization data is presented, interpreted in terms of an assembly of superparamagnetic moments developing in the dense distribution of clusters.
Journal ArticleDOI
Cubic Rashba Spin-Orbit Interaction of a Two-Dimensional Hole Gas in a Strained- Ge / SiGe Quantum Well
Rai Moriya,Kentarou Sawano,Yusuke Hoshi,Yusuke Hoshi,Satoru Masubuchi,Yasuhiro Shiraki,Andreas Wild,Andreas Wild,Christian Neumann,Gerhard Abstreiter,Dominique Bougeard,Takaaki Koga,Tomoki Machida +12 more
TL;DR: The findings reveal that the heavy hole in strained Ge is a purely cubic Rashba system, which is consistent with the spin angular momentum m(j) = ± 3/2 nature of the HH wave function.
Journal ArticleDOI
Raman characterization of strain and composition in small-sized self-assembled Si/Ge dots
TL;DR: In this paper, the structural properties of Si/Ge dot multilayers are characterized in Raman spectra. And the results show that the Si-Ge and Ge-Si modes can be used as an efficient way to determine the average strain and composition in uncorrelated small-sized si/Ge dots in which the mean strain field is close to biaxial case.
