CE-antiferromagnetic electronic structure in LaSrMnO revealed by micro-focused angle-resolved photoemission spectroscopy and tight-binding models
Yasutaka Sawata, Yudai Hirai, Rintaro Miyabayashi +7
We have investigated the electronic structure of LaSrMnO in the CE-type antiferromagnetic (CE-AFM) state below the Néel temperature using micro-focused angle-resolved…
Direct observation of band structure modifications from monolayer WSe2 to Janus WSSe
Masato Sakano, Shunsuke Akatsuka, Takato Yamamoto +19
Janus monolayer transition metal dichalcogenides (TMDs), created by post-growth substitution of the top chalcogen layer, represent a new direction for engineering 2D crystal proper…
Spectroscopic Evidence for Electron-Boson Coupling in Half-metallic CrO2
Daiki Ootsuki, Hirokazu Fujiwara, Noriyuki Kataoka +9
We report quasiparticle properties of the half-metal ferromagnet CrO2 by means of high-resolution angle-resolved photoemission spectroscopy (ARPES). We clearly observed the Fermi s…

Daiki Ootsuki, Akitoshi Nakano, Urara Maruoka +6
We report the electronic structure of the thermoelectric semimetal TaPdSe with a large thermoelectric power factor and giant Peltier conductivity by means of angle-resolved…
Unveiling two-dimensional electron systems on ultra-wide bandgap semiconductor -GaO
Ryu Yukawa, Hiroshi Mizuseki, Suryo Santoso Putro +26
Ultra-wide bandgap (UWBG) semiconductors promise to revolutionize power electronics, yet a fundamental understanding of their interfacial electronic structure has been hindered by…
