Anisotropic Behavior of the Thermoelectric Power and the Thermal Conductivity in a Unidirectional Lateral Superlattice: A Typical Anisotropic System Exhibiting Two Distinct Nernst Coefficients
Akira Endo, Shingo Katsumoto, Yasuhiro Iye
We have calculated the thermoelectric conductivity tensor and the thermal conductivity tensor of a unidirectional lateral superlattice (ULSL) ($i,j = x,…
Joule heating and the thermal conductivity of a two-dimensional electron gas at cryogenic temperatures studied by modified 3 method
Akira Endo, Shingo Katsumoto, Yasuhiro Iye
During the standard ac lock-in measurement of the resistance of a two-dimensional electron gas (2DEG) applying an ac current , the electron temperature $…
Commensurability oscillations in the Hall resistance of unidirectional lateral superlattices
Akira Endo, Shingo Katsumoto, Yasuhiro Iye
We have observed commensurability oscillations (CO) in the Hall resistance of a unidirectional lateral superlattice (ULSL). The CO, having small amplitudes ( 1 )…
Spatial distribution of thermoelectric voltages in a Hall-bar shaped two-dimensional electron system under a magnetic field
Akira Endo, Kazuhiro Fujita, Shingo Katsumoto +1
We have investigated the spatial distribution of the electron temperature generated in a two-dimensional electron system (2DES) subjected to a perpendicular magnetic field. We meas…
Frequencies of the Edge-Magnetoplasmon Excitations in Gated Quantum Hall Edges
Akira Endo, Keita Koike, Shingo Katsumoto +1
We have investigated microwave transmission through the edge of quantum Hall systems by employing a coplanar waveguide (CPW) fabricated on the surface of a GaAs/AlGaAs two-dimensio…
Diffusion Thermopower of Quantum Hall States Measured in Corbino Geometry
Shuhei Kobayakawa, Akira Endo, Yasuhiro Iye
We have measured the diffusion thermopower of a quantum Hall system in a Corbino setup. A concentric electron-temperature gradient is introduced by irradiating microwaves, via a co…
