Identification of electronic dimensionality reduction in semiconductor quantum well structures
Takahito Takeda, Kengo Takase, Vladimir N. Strocov +2
Two-dimensional (2D) systems, such as high-temperature superconductors, surface states of topological insulators, and layered materials, have been intensively studied using vacuum-…
Ferromagnetism induced by hybridization of Fe 3d orbitals with ligand InSb bands in n-type ferromagnetic semiconductor (In,Fe)Sb
Ryo Okano, Tomoki Hotta, Takahito Takeda +8
Fe-doped III-V ferromagnetic semiconductor (FMS) (In,Fe)Sb is a promising material for spintronic device applications because of the n-type carrier conduction and the ferromagnetis…
Growth and characterization of quaternary-alloy ferromagnetic semiconductor (In,Ga,Fe)Sb
Tomoki Hotta, Kengo Takase, Kosuke Takiguchi +3
We study the growth and properties of quaternary-alloy ferromagnetic semiconductor (FMS) (In0.94-x,Gax,Fe0.06)Sb (x = 5% - 30%, Fe concentration is fixed at 6%) grown by low temper…
Elemental topological Dirac semimetal α-Sn with high quantum mobility
Le Duc Anh, Kengo Takase, Takahiro Chiba +3
α-Sn with a diamond-type crystal structure provides an ideal avenue to investigate novel topological properties owing to its rich diagram of topological phases and simple elemental…
Current-in-plane spin-valve magnetoresistance in ferromagnetic semiconductor (Ga,Fe)Sb heterostructures with high Curie temperature
Kengo Takase, Le Duc Anh, Kosuke Takiguchi +1
We demonstrate spin-valve magnetoresistance with a current-in-plane (CIP) configuration in (Ga,Fe)Sb / InAs (thickness nm) / (Ga,Fe)Sb trilayer heterostructures,…
