Key role of lattice symmetry in the metal-insulator transition of NdNiO3 films
Jack Y. Zhang, Honggyu Kim, Evgeny Mikheev +2
Bulk NdNiO3 exhibits a metal-to-insulator transition (MIT) as the temperature is lowered that is also seen in tensile strained films. In contrast, films that are under a large comp…
Carrier density independent scattering rate in SrTiO3-based electron liquids
Evgeny Mikheev, Santosh Raghavan, Jack Y. Zhang +4
We examine the carrier density dependence of the scattering rate in two- and three-dimensional electron liquids in SrTiO3 in the regime where it scales with T^n (T is the temperatu…
High-density two-dimensional small polaron gas in a delta-doped Mott insulator
Daniel G. Ouellette, Pouya Moetakef, Tyler A. Cain +4
Heterointerfaces in complex oxide systems open new arenas in which to test models of strongly correlated material, explore the role of dimensionality in metal-insulator-transitions…
Gaps and pseudo-gaps at the Mott quantum Critical point in the perovskite rare earth nickelates
S. James Allen, Adam J. Hauser, Evgeny Mikheev +8
We report on tunneling measurements that reveal for the first time the evolution of the quasi-particle state density across the bandwidth controlled Mott metal to insulator transit…
Correlation between metal-insulator transitions and structural distortions in high-electron-density SrTiO3 quantum wells
Jack Y. Zhang, Clayton A. Jackson, Ru Chen +4
The electrical and structural characteristics of SmTiO3/SrTiO3/SmTiO3 and GdTiO3/SrTiO3/GdTiO3 heterostructures are compared. Both types of structures contain narrow SrTiO3 quantum…
Magnetism and local structure in low-dimensional, Mott insulating GdTiO3
Jack Y. Zhang, Clayton A. Jackson, Santosh Raghavan +2
Cation displacements, oxygen octahedral tilts, and magnetism of epitaxial, ferrimagnetic, insulating GdTiO3 films sandwiched between cubic SrTiO3 layers are studied using scanning…
Structural origins of the properties of rare earth nickelate superlattices
Jinwoo Hwang, Junwoo Son, Jack Y. Zhang +3
NiO6 octahedral tilts in the LaNiO3/SrTiO3 superlattices are quantified using position averaged convergent beam electron diffraction in scanning transmission electron microscopy. I…
Nanoscale Quantification of Octahedral Tilts in Perovskite Films
Jinwoo Hwang, Jack Y. Zhang, Junwoo Son +1
NiO6-octahedral tilts in ultrathin LaNiO3 films were studied using position averaged convergent beam electron diffraction (PACBED) in scanning transmission electron microscopy. Bot…
Electrostatic carrier doping of GdTiO3/SrTiO3 interfaces
Pouya Moetakef, Tyler A. Cain, Daniel G. Ouellette +7
Heterostructures and superlattices consisting of a prototype Mott insulator, GdTiO3, and the band insulator SrTiO3 are grown by molecular beam epitaxy and show intrinsic electronic…
