Strong evidence for d-electron spin transport at room temperature at a LaAlO3/SrTiO3 interface
Ryo Ohshima, Yuichiro Ando, Kosuke Matsuzaki +8
A d-orbital electron has an anisotropic electron orbital and is a source of magnetism. The realization of a 2-dimensional electron gas (2DEG) embedded at a LaAlO3/SrTiO3 interface…
Electronic charges and electric potential at LaAlO3/SrTiO3 interfaces studied by core-level photoemission spectroscopy
M. Takizawa, S. Tsuda, T. Susaki +2
We studied LaAlO3/SrTiO3 interfaces for varying LaAlO3 thickness by core-level photoemission spectroscopy. In Ti 2p spectra for conducting "n-type" interfaces, Ti3+ signals appeare…
Two-Dimensional Confinement of 3d1 Electrons in LaTiO3/LaAlO3 Multilayers
S. S. A. Seo, M. J. Han, G. W. J. Hassink +12
We report spectroscopic ellipsometry measurements of the anisotropy of the interband transitions parallel and perpendicular to the planes of (LaTiO3)n(LaAlO3)5 multilayers with n =…
Modulation Doping of a Mott Quantum Well by a Proximate Polar Discontinuity
T. Higuchi, Y. Hotta, T. Susaki +2
We present evidence for hole injection into LaAlO3/LaVO3/LaAlO3 quantum wells near a polar surface of LaAlO3 (001). As the surface is brought in proximity to the LaVO3 layer, an ex…
Remote hole-doping of Mott insulators on the nanometer scale
M. Takizawa, Y. Hotta, T. Susaki +12
At interfaces between polar and nonpolar perovskite oxides, an unusual electron-doping has been previously observed, due to electronic reconstructions. We report on remote hole-dop…
Negative Differential Resistance Induced by Mn Substitution at SrRuO3/Nb:SrTiO3 Schottky Interfaces
Y. Hikita, L. Fitting Kourkoutis, T. Susaki +3
We observed a strong modulation in the current-voltage characteristics of SrRuO/Nb:SrTiO Schottky junctions by Mn substitution in SrRuO, which induces a metal-insulator…
