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…
