Acoustic Localization Phenomena in Ferroelectric Nanophononic Devices
A. Bruchhausen, N. D. Lanzillotti-Kimura, B. Jusserand +4
The engineering of phononic resonances in ferroelectric structures appears as a new knob in the design and realization of novel multifunctional devices. In this work we experimenta…
Polarization dependence of coherent phonon generation and detection in the 3D topological insulator Bi2Te3
O. V. Misochko, J. Flock, T. Dekorsy
We have studied the polarization dependence of coherent phonons in the topological insulator Bi2Te3. Using polarization-dependent femtosecond pump-probe spectroscopy, we measured c…
Observation of Zone-Folded Acoustic Phonons in Terahertz Quantum Cascade Lasers using Picosecond Ultrasonics
Axel Bruchhausen, Mike Hettich, James Lloyd-Hughes +5
We have investigated the time-resolved vibrational properties of terahertz quantum cascade lasers by means of ultra-fast laser spectroscopy. By the observation of the acoustic fold…
Sub-harmonic resonant excitation of confined acoustic modes at GHz frequencies with a high-repetition-rate femtosecond laser
A. Bruchhausen, R. Gebs, F. Hudert +10
We propose sub-harmonic resonant optical excitation with femtosecond lasers as a new method for the characterization of phononic and nanomechanical systems in the gigahertz to tera…
Evidence for a Structurally-driven Insulator-to-metal Transition in VO2: a View from the Ultrafast Timescale
A. Cavalleri, Th. Dekorsy, H. H. Chong +2
We apply ultrafast spectroscopy to establish a time-domain hierarchy between structural and electronic effects in a strongly-correlated electron system. We discuss the case of the…
