Ultrafast scattering dynamics of coherent phonons in BiSb in the Weyl semimetal phase
Yuta Komori, Yuta Saito, Paul Fons +1
We investigate ultrafast phonon dynamics in the BiSb alloy system for various compositions using a reflective femtosecond pump-probe technique. The coherent optic…
The effect of ion irradiation on dephasing of coherent optical phonons in GaP
Takuto Ichikawa, Yuta Saito, Muneaki Hase
The dephasing of coherent longitudinal optical (LO) phonons in ion-irradiated GaP has been investigated with a femtosecond pump-probe technique based on electro-optic sampling. The…
Ultrafast dynamics of the low frequency shear mode in
T. Fukuda, K. Makino, Y. Saito +4
We report on the dynamics of coherent phonons in semimetal 1T'-MoTe2 using femtosecond pump-probe spectroscopy. On an ultrafast sub-picosecond time scale at room temperature, a low…
All-optical detection of periodic structure of chalcogenide superlattice using coherent folded acoustic phonons
Takara Suzuki, Yuta Saito, Paul Fons +3
Chalcogenide superlattices (SL) consist of alternate stacking of GeTe and SbTe layers. The structure can become a 3D topological insulator depending on the constituent…
A topological phase buried in a chalcogenide superlattice monitored by a helicity dependent Kerr measurement
Richarj Mondal, Yuki Aihara, Yuta Saito +4
Chalcogenide superlattices (SL), formed by the alternate stacking of GeTe and SbTe layers, also referred to as interfacial phase change memory (iPCM), are a leading can…
Photon Energy Dependence of Kerr Rotation in Chalcogenide Superlattices
Takara Suzuki, Richarj Mondal, Yuta Saito +5
We report on pump-probe based helicity dependent time-resolved Kerr measurements of chalcogenide superlattices, consisting of alternately stacked GeTe and SbTe layers u…
