Parity-dependent shot noise and spin-flip relaxation process in a hybrid superconductor-nanowire quantum dot
Keiko Takase, Yasuhiro Utsumi, Yamato Ashikawa +4
We report shot noise measurements for a quantum dot formed in an InAs nanowire suspended between superconducting electrodes. We find a clear alternation for the shot noise value in…
Electrical tuning of the spin-orbit interaction in nanowire by transparent ZnO gate grown by atomic layer deposition
Keiko Takase, Kouta Tateno, Satoshi Sasaki
We develop an InAs nanowire gate-all-around field-effect transistor using a transparent conductive zinc oxide (ZnO) gate electrode, which is in-situ atomic layer deposited after gr…
Atomic Layer Deposition of Aluminum (111) Thin Film by Dimethylethylaminealane Precursor
Sameh Okasha, Yoshiaki Sekine, Satoshi Sasaki +1
We report the growth of aluminum (111) thin film by atomic layer deposition (ALD) technique with dimethylethylaminealane (DMEAA) as a precursor. It is found that the metallic under…
Suppression of Gate Screening on Edge Magnetoplasmons by Highly Resistive ZnO Gate
N. Kumada, N. -H. Tu, K. -i. Sasaki +5
We investigate a way to suppress high-frequency coupling between a gate and low-dimensional electron systems in the gigahertz range by measuring the velocity of edge magnetoplasmon…
Spintronic superconductor in a bulk layered material with natural spin-valve structure
Shunsuke Sakuragi, S. Sasaki, R. Akashi +29
Multi-layered materials provide fascinating platforms to realize various functional properties, possibly leading to future electronic devices controlled by external fields. In part…
Active spatial control of terahertz graphene plasmons by tailoring carrier density profile
Ngoc Han Tu, Katsumasa Yoshioka, Satoshi Sasaki +3
Graphene offers a possibility for actively controlling plasmon confinement and propagation by tailoring its spatial conductivity pattern. However, implementation of this concept ha…
