Journal ArticleDOI
Three-dimensional Si/Ge quantum dot crystals.
Detlev Grützmacher,Thomas Fromherz,Christian Dais,Julian Stangl,Elisabeth Müller,Yasin Ekinci,Harun H. Solak,H. Sigg,Rainer T. Lechner,E. Wintersberger,Stefan Birner,Václav Holý,Gerrit E. W. Bauer +12 more
TL;DR: An up to now unmatched structural perfection of the quantum dot crystal and a narrow quantum dot size distribution are revealed, indicating a low defect density in the three-dimensional SiGe quantum dot crystals.
Journal ArticleDOI

M Könnecke,Frederick Akeroyd,Herbert J. Bernstein,Aaron S. Brewster,Stuart I. Campbell,Bjørn Clausen,Stephen P. Cottrell,Jens Uwe Hoffmann,Pete R. Jemian,David Mannicke,Raymond Osborn,Peter F. Peterson,Tobias Richter,Jiro Suzuki,Benjamin Watts,E. Wintersberger,Joachim Wuttke +16 more
TL;DR: A description of the NeXus data format for X-ray and neutron scattering and muon spectroscopy is presented.
Journal ArticleDOI
xrayutilities: a versatile tool for reciprocal space conversion of scattering data recorded with linear and area detectors
TL;DR: Algorithms for the reciprocal space conversion of linear and area detectors are implemented in an open-source Python package and show good results in terms of accuracy and efficiency.
Journal ArticleDOI
Raman spectroscopy determination of composition and strain in Si1-xGex/Si heterostructures
Fabio Pezzoli,Emiliano Bonera,Emanuele Grilli,Mario Guzzi,Stefano Sanguinetti,Daniel Chrastina,Giovanni Isella,H. von Känel,E. Wintersberger,J. Stangl,G. Bauer +10 more
TL;DR: In this paper, a procedure for the quantitative measurement of composition and strain in epitaxial Si 1 - x Ge x / Si heterostructures by means of Raman spectroscopy for any Ge concentration is presented.
Journal ArticleDOI
Phonon strain shift coefficients in Si1−xGex alloys
Fabio Pezzoli,Emiliano Bonera,Emanuele Grilli,Mario Guzzi,Stefano Sanguinetti,D. Chrastina,Giovanni Isella,H. von Känel,E. Wintersberger,J. Stangl,G. Bauer +10 more
TL;DR: In this paper, a comprehensive study of the biaxial strain-induced shift of the Si1−xGex Raman active phonon modes is presented, which decouple and quantify separately the effect of strain and composition on the phonon frequencies.
