Large Zeeman Splitting in Out-of-Plane Magnetic Field in a Double-Layer Quantum Point Contact
D. Terasawa, S. Norimoto, T. Arakawa +4
In this study, we observe that the conductance of a quantum point contact on a GaAs/AlGaAs double quantum well depends significantly on the magnetic field perpendicular to the two-…
Conductance quantization and shot noise of a double-layer quantum point contact
D. Terasawa, S. Norimoto, T. Arakawa +4
The conductance quantization and shot noise below the first conductance plateau are measured in a quantum point contact fabricated in a GaAs/AlGaAs tunnel-coupled do…
Temperature dependence of universal conductance fluctuation due to development of weak localization in graphene
D. Terasawa, A. Fukuda, A. Fujimoto +2
The temperature effect of quantum interference on resistivity is examined in monolayer graphene, with experimental results showing that the amplitude of the conductance fluctuation…
Relationship between conductance fluctuation and weak localization in graphene
D. Terasawa, A. Fukuda, A. Fujimoto +3
The relationship between the universal conductance fluctuation and the weak localization effect in monolayer graphene is investigated. By comparing experimental results with the pr…
Phase Transition to Insulating State from Quantum Hall State by Current-Induced Nuclear Spin Polarization
Shibun Tsuda, Minh-Hai Nguyen, Daiju Terasawa +2
We investigate the resistance enhancement state (RES) where the magnetoresistance of the fractional quantum Hall state (FQHS) is increased with dynamic nuclear spin polari…
Interlayer Diffusion of Nuclear Spin Polarization in Quantum Hall States
Minh-Hai Nguyen, Shibun Tsuda, Daiju Terasawa +3
At the spin transition point of quantum Hall states, nuclear spins in a two-dimensional electron gas are polarized by an electric current. Using GaAs/AlGaAs double-quantum-…
