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…
Dispersive detection of a charge qubit with a broadband high-impedance quantum-Hall plasmon resonator
Chaojing Lin, Kosei Teshima, Takafumi Akiho +2
Cavity quantum electrodynamics (cQED) provides strong light-matter interactions that can be used for manipulating and detecting quantum states. The interaction can be enhanced by i…
Effects of GaAs Buffer Layer on Structural, Magnetic, and Transport Properties of Magnetic Topological Insulators Cr(BiSb)Te and V(BiSb)Te Films
Yusuke Nakazawa, Takafumi Akiho, Kiyoshi Kanisawa +3
Here, we study the effects of a GaAs buffer layer on the structural, magnetic, and transport properties of Cr(BiSb)Te magnetic topological insulator thi…
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…
Effects of GaAs buffer layer on quantum anomalous Hall insulator Vy(BixSb1-x)2-yTe3
Yusuke Nakazawa, Takafumi Akiho, Kiyoshi Kanisawa +3
We report the growth, structural characterization, and transport properties of the quantum anomalous Hall insulator Vy(BixSb1-x)2-yTe3 (VBST) grown on a GaAs buffer layer by molecu…
Andreev reflection of fractional quantum Hall quasiparticles
Masayuki Hashisaka, Thibaut Jonckheere, Takafumi Akiho +4
Electron correlation in a quantum many-body state appears as peculiar scattering behaviour at its boundary, symbolic of which is Andreev reflection at a metal-superconductor interf…
A vertical diatomic artificial molecule in the intermediate coupling regime in a parallel and perpendicular magnetic field
F. Ancilotto, D. G. Austing, M. Barranco +4
We present experimental results for the ground state electrochemical potentials of a few electron semiconductor artificial molecule made by vertically coupling two quantum dots, in…
