Toward Wearable Biosensing by Spectroscopy-free Raman Shift Detection and Soft Optofluidics
This thesis introduces spectroscopy-free Raman biosensing, which may find increasing use in the next generation of wearable devices for preventive healthcare. While wearables have made substantial advancements in detecting physical biomarkers, they have ye ...
EPFL2024Quantum state-resolved methane scattering from Ni(111) and NiO(111) by bolometer infrared laser tagging: The effect of surface oxidation
Rainer Beck, Christopher Scott Reilly, Bo-Jung Chen, Patrick Floss
We describe a novel UHV state-to-state molecule/surface scattering apparatus with quan- tum state preparation of the incident molecular beam and angle-resolved quantum state detection of the scattered molecules. State resolved detection is accomplished usi ...
2023Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Raw data associated to the manuscript ‘’Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies‘’, Physical Review Materials 7, 054407(2023); doi: 10.1103/PhysRevMaterials.7.054407 Information about file fo ...
Zenodo2023Charging and Electric Field Effects on Hydrogen Molecules Physisorbed on Graphene
Klaus Kern, Shai Mangel, Alessio Scavuzzo, Tobias Wollandt
Molecular hydrogen adsorbed on graphene was investigated by analyzing rotational excitation spectra obtained with a gate-tunable scanning tunneling microscope (STM). Through the shift of the rotational excitation energy, the tunability of physisorbed H2 on ...
AMER CHEMICAL SOC2023Spin wave dispersion of ultra-low damping hematite ( α−Fe2O3 ) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Low magnetic damping and high group velocity of spin waves (SWs) or magnons are two crucial parameters for functional magnonic devices. Magnonics research on signal processing and wave-based computation at GHz frequencies focused on the artificial ferrimag ...
2023Reconfigurable nonreciprocal excitation of propagating exchange spin waves in perpendicularly magnetized yttrium iron garnet thin films
Jean-Philippe Ansermet, Haiming Yu, Yu Zhang, Peng Chen, Jilei Chen, Tao Liu, Jinlong Wang, Rundong Yuan
We report the nonreciprocal excitation of propagating forward volume exchange spin waves in yttrium iron garnet (YIG) thin film with perpendicular anisotropy by bringing the in-plane magnetization of Co20Fe60B20 (CoFeB) nanowires to resonance. All-electric ...
College Pk2023Fast, Broad-Band Magnetic Resonance Spectroscopy with Diamond Widefield Relaxometry
Mayeul Sylvain Chipaux, Hoda Shirzad
We present an alternative to conventional Electron the use of bulky magnets and magnetron equipment, we use the photoluminescence of an ensemble of Nitrogen-Vacancy centers at the surface of a diamond. Monitoring their relaxation time (or T1), we detected ...
