Delta-doped SrTiO3 top-gated field effect transistor Open
Oxide heterostructures are an attractive platform for incorporation in field-effect transistors (FETs) due to their diverse physical properties which can be tuned by electrostatic gating. We report a top-gated FET based on a SrTiO3 delta-d…

Carrier density and disorder tuned superconductor-metal transition in a two-dimensional electron system Open
Quantum ground states that arise at atomically controlled oxide interfaces provide an opportunity to address key questions in condensed matter physics, including the nature of two-dimensional metallic behaviour often observed adjacent to s…

Polaronic behavior in a weak-coupling superconductor Open
Significance The perovskite oxide SrTiO3 is an n-type semiconductor, which exhibits superconductivity at low temperatures even though there are extraordinarily few electrons. In most materials, with so few electrons it becomes difficult to…

Strain Tuning in Complex Oxide Epitaxial Films Using an Ultrathin Strontium Aluminate Buffer Layer Open
A reliable method to apply biaxial strain over a wide range of values with minimal dislocation generation is critical for the study of strain dependent physical properties in oxide thin films and heterostructures. In this work, we systemat…

Defect Control of Conventional and Anomalous Electron Transport at Complex Oxide Interfaces Open
Using low-temperature electrical measurements, the interrelation between electron transport, magnetic properties, and ionic defect structure in complex oxide interface systems is investigated, focusing on NdGaO3/SrTiO3 (100) interfaces. Fi…

Depth resolved domain mapping in tetragonal SrTiO3 by micro-Laue diffraction Open
We present depth resolved X-ray micro-Laue diffraction experiments on the low temperature domain structure of SrTiO3. At 80 K, monochromatic X-ray diffraction shows an elongated out-of-plane unit cell axis within a matrix of in-plane orien…
