Crystal structure built from a GeO $_{6}$ -GeO $_{5}$ polyhedra network with high thermal stability: $β$ -SrGe $_{2}$ O $_{5}$

Christian A. Niedermeier, Jun-ichi Yamaura, Jiazhen Wu +4

By tackling the challenge of extending transparent oxide semiconductors to Ge based oxides, we have found a not-yet-reported crystal structure, named $β$ -SrGe $_{2}$ O $_{5}$ , which is co…

Shallow Valence Band of Rutile GeO $_{2}$ and P-type Doping

Christian A. Niedermeier, Keisuke Ide, Takayoshi Katase +2

GeO $_{2}$ has an $α$ -quartz-type crystal structure with a very wide fundamental band gap of 6.6 eV and is a good insulator. Here we find that the stable rutile-GeO $_{2}$ polymorph with…

Phonon scattering limited mobility in the representative cubic perovskite semiconductors SrGeO $_{3}$ , BaSnO $_{3}$ and SrTiO $_{3}$

Christian A. Niedermeier, Yu Kumagai, Keisuke Ide +4

Cubic perovskite oxides are emerging high-mobility transparent conducting oxides (TCOs), but Ge-based TCOs had not been known until the discovery of metastable cubic SrGeO $_{3}$ . $0.…

Electron effective mass and mobility limits in degenerate perovskite stannate BaSnO $_{3}$

Christian A. Niedermeier, Sneha Rhode, Keisuke Ide +4

The high room temperature mobility and the electron effective mass in BaSnO $_{3}$ are investigated in depth by evaluation of the free carrier absorption observed in infrared spectra…
