Coexistence of Donor and Acceptor Hydrogen States in n-Type InN
Masaki Kobayashi, Yudai Yamashita, Kazuyuki Hirama +1
Hydrogen often exhibits amphoteric behavior in semiconductors, but its role is in n-type InN remains unresolved. Wurtzite InN is a narrow-gap semiconductor with high electron mobil…
Intrinsic low-spin state and strain-tunable anomalous Hall scaling in high-quality SrRuO3 (111) films
Harunori Shiratani, Yuki K. Wakabayashi, Yoshiharu Krockenberger +6
The (111)-oriented 4d ferromagnetic perovskite SrRuO3 (SRO) offers a unique triangular-lattice geometry, making it a promising platform for exploring Berry-curvature-driven and spi…
Orbital-resolved anisotropic electron pockets in electron-doped SrTiO3 observed by ARPES
Yuki K. Wakabayashi, Akihira Munakata, Yoshitaka Taniyasu +1
SrTiO3 has attracted considerable interest as a wide-band gap semiconductor for advanced high-k capacitors and photocatalytic applications. Although previous angle-resolved photoem…
Single monolayer ferromagnetic perovskite SrRuO3 with high conductivity and strong ferromagnetism
Yuki K. Wakabayashi, Masaki Kobayashi, Yoshiharu Krockenberger +4
Achieving robust ferromagnetism and high conductivity in atomically thin oxide materials is critical for advancing spintronic technologies. Here, we report the growth of a highly c…
