Nanostructure Investigations of Nonlinear Differential Conductance in NdNiO Thin Films
Will J. Hardy, Heng Ji, Evgeny Mikheev +2
Transport measurements on thin films of NdNiO reveal a crossover to a regime of pronounced nonlinear conduction below the well-known metal-insulator transition temperature. The…
Surface Reconstructions in Molecular Beam Epitaxy of SrTiO3
Adam P. Kajdos, Susanne Stemmer
We show that reflection high-energy electron diffraction (RHEED) can be used as a highly sensitive tool to track surface and resulting film stoichiometry in adsorption-limited mole…
Au-Gated SrTiO3 Field-Effect Transistors with Large Electron Concentration and Current Modulation
Amit Verma, Santosh Raghavan, Susanne Stemmer +1
We report the fabrication of low-leakage rectifying Pt and Au Schottky diodes and Au-gated metal-semiconductor field effect transistors (MESFETs) on n-type SrTiO3 thin films grown…
Intrinsic Mobility Limiting Mechanisms in Lanthanum-doped Strontium Titanate
Amit Verma, Adam P. Kajdos, Tyler A. Cain +2
The temperature dependent Hall mobility data from La-doped SrTiO3 thin films has been analyzed and modeled considering various electron scattering mechanisms. We find that a ~6 meV…
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…
