Scattering-dependent transport of SrRuO3 films: From Weyl fermion transport to hump-like Hall effect anomaly
Shingo Kaneta-Takada, Yuki K. Wakabayashi, Yoshiharu Krockenberger +5
Recent observation of quantum transport phenomena of Weyl fermions has brought much attention to 4d ferromagnetic perovskite SrRuO3 as a magnetic Weyl semimetal. Besides, the hump-…
Time-resolved measurement of ambipolar edge magnetoplasmon transport in InAs/InGaSb composite quantum wells
Hiroshi Kamata, Hiroshi Irie, Norio Kumada +1
Time-resolved charge transport measurement for one-dimensional edge states is a powerful means for investigating nonequilibrium charge dynamics and underlying interaction effects t…
Single-domain perpendicular magnetization induced by the coherent O 2p-Ru 4d hybridized state in an ultra-high-quality SrRuO3 film
Yuki K. Wakabayashi, Masaki Kobayashi, Yukiharu Takeda +8
We investigated the Ru 4d and O 2p electronic structure and magnetic properties of an ultra-high-quality SrRuO3 film on SrTiO3 grown by machine-learning-assisted molecular beam epi…
High-mobility two-dimensional carriers from surface Fermi arcs in magnetic Weyl semimetal films
Shingo Kaneta-Takada, Yuki K. Wakabayashi, Yoshiharu Krockenberger +10
High-mobility two-dimensional carriers originating from surface Fermi arcs in magnetic Weyl semimetals are highly desired for accessing exotic quantum transport phenomena and for t…
Energy gap tuning and gate-controlled topological phase transition in InAs/InGaSb composite quantum wells
H. Irie, T. Akiho, F. Couëdo +3
We report transport measurements of strained InAs/InGaSb composite quantum wells (CQWs) in the quantum spin Hall phase, focusing on the control of the energy gap thro…
Determination of -factor in InAs two-dimensional electron system by capacitance spectroscopy
Hiroshi Irie, Takafumi Akiho, Koji Muraki
We determine the effective -factor () of a two-dimensional electron gas (2DEG) using a new method based on capacitance spectroscopy. The capacitance-voltage profile of…
