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…
Zener Tunneling Breakdown in Phase-Change Materials Revealed by Intense Terahertz Pulses
Yasuyuki Sanari, Takehiro Tachizaki, Yuta Saito +8
We have systematically investigated the spatial and temporal dynamics of crystallization that occurs in the phase-change material Ge2Sb2Te5 upon irradiation with an intense THz pul…
Ultrafast Dynamics of Electron-phonon Coupling in Transition-metal Dichalcogenides
Kotaro Makino, Yuta Saito, Shuuto Horii +6
Time-domain femtosecond laser spectroscopic measurements of the ultrafast lattice dynamics in 2H-MoTe2 bulk crystals were carried out to understand the carrier-phonon interactions…
