Nonlinear Hall effect and multichannel conduction in LaTiO3/SrTiO3 superlattices
J. S. Kim, S. S. A. Seo, M. F. Chisholm +4
We report magneto-transport properties of heterointerfaces between the Mott insulator LaTiO3 and the band insulator SrTiO3 in a delta-doping geometry. At low temperatures, we have…
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 =…
Multiple conducting carriers generated in LaAlO3/SrTiO3 heterostructures
S. S. A. Seo, Z. Marton, W. S. Choi +6
We have found that there is more than one type of conducting carriers generated in LaAlO3/SrTiO3 heterostructures by comparing the sheet carrier density and mobility from optical t…
Effects of oxygen-reducing atmosphere annealing on LaMnO epitaxial thin films
W S Choi, Z Marton, S Y Jang +8
We investigated the effects of annealing on LaMnO epitaxial thin films grown by pulsed laser deposition and propose an efficient method of characterizing their stoichiometry. S…
