Phonon scattering limited mobility in the representative cubic perovskite semiconductors SrGeO, BaSnO and SrTiO
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. $0.…
Electron effective mass and mobility limits in degenerate perovskite stannate BaSnO
Christian A. Niedermeier, Sneha Rhode, Keisuke Ide +4
The high room temperature mobility and the electron effective mass in BaSnO are investigated in depth by evaluation of the free carrier absorption observed in infrared spectra…
Enhanced critical-current in P-doped BaFe2As2 thin films on metal substrates arising from poorly aligned grain boundaries
Hikaru Sato, Hidenori Hiramatsu, Toshio Kamiya +1
Thin films of the iron-based superconductor BaFe2(As1-xPx)2 (Ba122:P) were fabricated on polycrystalline metal-tape substrates with two kinds of in-plane grain boundary alignments…
Novel solid-phase epitaxy for multi-component materials with extremely high vapor pressure elements: An application to KFe2As2
Taisuke Hatakeyama, Hikaru Sato, Hidenori Hiramatsu +2
We propose a novel solid-phase epitaxy technique applicable to high annealing temperatures up to 1000 C without re-vaporization of alkali metal elements with high vapor pressures.…
