Systematic study of superconductivity in few-layer -MoTe
Taro Wakamura, Masayuki Hashisaka, Yusuke Nomura +7
We present a systematic investigation of superconductivity in a topological superconductor candidate -MoTe in the few-layer limit. By examining multiple mechanically…
Intrinsic ultrafast edge photocurrent dynamics in WTe driven by broken crystal symmetry
Subhashri Chatterjee, Katsumasa Yoshioka, Taro Wakamura +2
Directional photocurrents in two-dimensional materials arise from broken crystal symmetry, offering pathways to high-speed, bias-free photodetection beyond conventional devices. Tu…
Super-diffusive sub-picosecond extraction of hot carriers in black phosphorous
Katsumasa Yoshioka, Taro Wakamura, Takuya Okamoto +1
Harvesting hot carriers before they lose energy to the lattice is a critical route toward surpassing the conventional thermodynamic limit in optical-to-electrical (O-E) conversion.…
Andreev Reflection in the Quantum Hall Regime at an Al/InAs Junction on a Cleaved Edge
Takafumi Akiho, Hiroshi Irie, Yusuke Nakazawa +3
We have fabricated a superconductor/semiconductor (S/Sm) junction composed of Al and InAs using cleaved edge overgrowth. By exploiting the unique geometry with a thin Al/Pt/Al tril…
Mach-Zehnder interference of fractionalized electron-spin excitations
Takase Shimizu, Eiki Iyoda, Satoshi Sasaki +4
Inter-channel Coulomb interaction mixes charge excitations in copropagating quantum Hall edge channels, generating coupled excitation eigenmodes propagating at different speeds. Th…
