Fabry-Pérot interference in a triple-gated quantum point contact
Shunta Maeda, Satoru Miyamoto, Mohammad H. Fauzi +3
We demonstrated that a triple-gated GaAs quantum point contact, which has an additional surface gate between a pair of split gates to strengthen the lateral confinement, produces t…
NMR Tracing of Hyperfine-Mediated Nuclear Spin Diffusion in Fractional Quantum Hall Domain Phases
S. Miyamoto, T. Hatano, S. Watanabe +1
We present an enhanced diffusion of nuclear spin polarization in fractional quantum Hall domain phases at . Resistively-detected NMR mediated by electrically driven domain-…
Localized NMR Mediated by Electrical-Field-Induced Domain Wall Oscillation in Quantum-Hall-Ferromagnet Nanowire
S. Miyamoto, T. Miura, S. Watanabe +2
We present fractional quantum Hall domain walls confined in a gate-defined wire structure. Our experiments utilize spatial oscillation of domain walls driven by radio frequency ele…
Resonant escape over an oscillating barrier in single-electron ratchet transfer
Satoru Miyamoto, Katsuhiko Nishiguchi, Yukinori Ono +2
Single-electron escape from a metastable state over an oscillating barrier is experimentally investigated in silicon-based ratchet transfer. When the barrier is oscillating on a ti…
Excitonic Aharonov-Bohm Effect in Isotopically Pure 70Ge/Si Type-II Quantum Dots
Satoru Miyamoto, Oussama Moutanabbir, Toyofumi Ishikawa +5
We report on a magneto-photoluminescence study of isotopically pure 70Ge/Si self-assembled type-II quantum dots. Oscillatory behaviors attributed to the Aharonov-Bohm effect are si…
