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…
Subband structure of two-dimensional electron gases in SrTiO3
Santosh Raghavan, S. James Allen, Susanne Stemmer
Tunneling between two parallel, two-dimensional electron gases (2DEGs) in a complex oxide heterostructure containing a large, mobile electron density of ~ 3x10^14 cm^-2 is used to…
Shubnikov-de Haas effect in low electron density SrTiO3: Conduction band edge of SrTiO3 redux
S James Allen, Bharat Jalan, SungBin Lee +5
The Shubnikov-de Haas effect is used to explore the conduction band edge of high mobility SrTiO3 films doped with La. The results largely confirm the earlier measurements by Uwe et…
Toward an artificial Mott insulator: Correlations in confined, high-density electron liquids in SrTiO3
Pouya Moetakef, Clayton A. Jackson, Jinwoo Hwang +3
We investigate correlation physics in high-density, two-dimensional electron liquids that reside in narrow SrTiO3 quantum wells. The quantum wells are remotely doped via an interfa…
Quantum oscillations from a two-dimensional electron gas at a Mott/band insulator interface
Pouya Moetakef, Daniel G. Ouellette, James R. Williams +4
We report on the magnetotransport properties of a prototype Mott insulator/band insulator perovskite heterojunction in magnetic fields up to 31 T and at temperatures between 360 mK…
