Rocksalt rare-earth monoxides as electronic and magnetic materials
Tomoteru Fukumura, Satoshi Sasaki, Masamichi Negishi +1
Stable binary rare earth (RE) oxides are usually trivalent RE ion sesquioxides (RE2O3), that are highly insulating and either nonmagnetic or antiferromagnetic. On the other hand, r…
Temperature dependent optical properties of -GaO thin films
T. Makino, S. Yusa, D. Oka +1
We determined the complex dielectric functions of -GaO using optical transmittance and reflectance spectroscopies at temperatures from 10 K to room temperature…
Photoreflectance spectroscopy of BiOCl epitaxial thin films
T. Nishiwaki, T. Makino, Z. Sun +2
We have observed a new optical transition in the photoreflectance spectra of indirect-gap BiOCl thin films, which were grown on SrTiO substrates. The position of this transitio…
Charge order with unusual star-of-David lattice in monolayer NbTe2
Taiki Taguchi, Katsuaki Sugawara, Hirofumi Oka +8
Interplay between fermiology and electron correlation is crucial for realizing exotic quantum phases. Transition-metal dichalcogenide (TMD) 1T-TaS2 has sparked a tremendous attenti…
Robust charge-density wave strengthened by electron correlations in monolayer 1T-TaSe2 and 1T-NbSe2
Yuki Nakata, Katsuaki Sugawara, Ashish Chainani +11
Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transitio…
Increased hole mobility in anti-ThCrSi-type LaOBi co-sintered with alkaline earth metal oxides for oxygen intercalation and hole carrier doping
Kota Matsumoto, Hideyuki Kawasoko, Noriaki Kimura +1
Metallic anti-ThCrSi-type OBi ( = rare earth) with Bi square nets show superconductivity while insulating LaOBi shows high hole mobility, by expanding…
