Phonon scattering mechanisms in WTe observed by ultrafast coherent phonon spectroscopy
Mizuki Akei, Yu Mizukoshi, Muneaki Hase
Revealing the mechanisms of phonon scattering is crucial for understanding material properties such as transport characteristics and optical responses. It can be discussed by measu…
An ultrafast diamond nonlinear photonic sensor
Daisuke Sato, Junjie Guo, Takuto Ichikawa +6
The integration of light and materials technology is key to the creation of innovative sensing technologies. Sensing of electric and magnetic fields, and temperature with high spat…
Role of interlayer shear phonons on lattice symmetry switching in the transition metal dichalcogenide WTe
Mizuki Akei, Takumi Fukuda, Yu Mizukoshi +2
Coherent phonon control using ultrashort pulse trains is the key to realizing structural phase transitions in solids by non-thermal pathways. By combining double-pulse excitation a…
Plasmon-enhanced ultrafast time-resolved spectroscopy of NV-containing diamond
Yuta Kimura, Toshu An, Muneaki Hase
We investigated ultrafast nonlinear optical effects in nitrogen-vacancy (NV)-containing diamond which is in contact with a gold-coated blazed diffraction grating using a pump-probe…
