Journal ArticleDOI
Characterization of thin-film adhesion and phonon lifetimes in Al/Si membranes by picosecond ultrasonics
Martin Grossmann,Martin Schubert,Chuan He,Delia Brick,Elke Scheer,Mike Hettich,Vitalyi Gusev,Thomas Dekorsy,Thomas Dekorsy +8 more
TL;DR: In this article, the authors quantitatively study interfacial adhesion in a two-layer membrane system consisting of Al and Si with femtosecond time-resolved laser spectroscopy.
Journal ArticleDOI
Spatial-temporally resolved high-frequency surface acoustic waves on silicon investigated by femtosecond spectroscopy
Martin F. Schubert,Martin Grossmann,Oliver Ristow,Mike Hettich,Axel Bruchhausen,Elaine C. S. Barretto,Elke Scheer,Vitalyi Gusev,Thomas Dekorsy +8 more
TL;DR: In this paper, Rayleigh and leaky longitudinal surface acoustic wave modes are detected in the time domain for various propagation distances by measuring on various pitches and comparing the spectra with finite element calculations.
Journal ArticleDOI
Femtosecond spectroscopy of acoustic frequency combs in the 100-GHz frequency range in Al/Si membranes
Martin Grossmann,Matthias Klingele,Patricia Scheel,Oliver Ristow,Mike Hettich,Chuan He,Reimar Waitz,Martin Schubert,Axel Bruchhausen,Vitalyi Gusev,Elke Scheer,Thomas Dekorsy +11 more
TL;DR: In this paper, a two-layer system with femtosecond pump-probe spectroscopy was analyzed and the damping times for the whole frequency range were determined.
Journal ArticleDOI
Investigation of coherent acoustic phonons in terahertz quantum cascade laser structures using femtosecond pump-probe spectroscopy
Axel Bruchhausen,James Lloyd-Hughes,Mike Hettich,Raphael Gebs,Martin Grossmann,Oliver Ristow,Albrecht Bartels,Milan Fischer,Matthias Beck,Giacomo Scalari,Jérôme Faist,Alok Rudra,Pascal Gallo,Eli Kapon,Thomas Dekorsy +14 more
TL;DR: In this paper, the acoustic dispersion of a terahertz quantum cascade laser structure (THz-QCLs) is characterized by folding of the dispersion into an effective reduced Brillouin zone, which allows the sample structure and periodicity to be determined with high precision on the order of 0.1%.
Journal ArticleDOI
Dynamics of coherent acoustic phonons in thin films of CoSb 3 and partially filled Yb x Co 4 Sb 12 skutterudites
Chuan He,M. Daniel,Martin Grossmann,Oliver Ristow,Delia Brick,Martin Schubert,Manfred Albrecht,Thomas Dekorsy +7 more
TL;DR: In this article, the authors demonstrate the generation and detection of coherent acoustic phonons in thin films of skutterudites and partially filled skatterudites using femtosecond pump-probe spectroscopy.
