Molecular beam epitaxy synthesis of ternary nitride PrTaN and its crystal structure determination
Kosuke Takiguchi, Yoshiharu Krockenberger, Eisuke Magome +2
We report the discovery of a novel ternary nitride PrTaN synthesized as a thin film using molecular beam epitaxy. The combination of e-beam evaporation for refractory elements…
Role of Ion Milling Angle in Determining Conducting and Insulating States on SrTiO3 Surfaces
Yuki K. Wakabayashia, Yoshiharu Krockenberger, Kosuke Takiguchi +2
SrTiO3 (STO), a promising wide-bandgap semiconductor for high-k capacitors and photocatalysis, requires precise surface control for device fabrication. This study investigates the…
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…
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…
Structural and transport properties of highly Ru-deficient SrRu0.7O3 thin films prepared by molecular beam epitaxy: comparison with stoichiometric SrRuO3
Yuki K. Wakabayashi, Shingo Kaneta-Takada, Yoshiharu Krockenberger +5
We investigate structural and transport properties of highly Ru-deficient SrRu0.7O3 thin films prepared by molecular beam epitaxy on (001) SrTiO3 substrates. To distinguish the inf…
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,…
