High-pressure phase diagram, structural transitions, and persistent non-metallicity of BaBiO: theory and experiment
Roman Martoňák, Davide Ceresoli, Tomoko Kagayama +3
BaBiO is a mixed-valence perovskite which escapes the metallic state through a Bi valence (and Bi-O bond) disproportionation or CDW distortion, resulting in a semiconductor wit…
Pressure-induced topological phase transition in polar semiconductor BiTeBr
Ayako Ohmura, Yuichiro Higuchi, Takayuki Ochiai +6
We performed X-ray diffraction and electrical resistivity measurement up to pressures of 5 GPa and the first-principles calculations utilizing experimental structural parameters to…
Pressure-induced phase transition of Bi2Te3 into the bcc structure
Mari Einaga, Ayako Ohmura, Atsuko Nakayama +3
The pressure-induced phase transition of bismuth telluride, Bi2Te3, has been studied by synchrotron x-ray diffraction measurements at room temperature using a diamond-anvil cell (D…
