Electronic Coupling of Metal-to-Insulator Transitions in Nickelate-Based Heterostructures
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
In rare earth nickelates, the metal-to-insulator transition observed as a function of temperature can be described using an electronic and a structural order parameter. The electronic one is linked to the electronic disproportionation observed below the tr ...
WILEY2023Metal-insulator transition in composition-tuned nickel oxide films
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
Thin films of the solid solution Nd1-xLaxNiO3 are grown in order to study the expected 0 K phase transitions at a specific composition. We experimentally map out the structural, electronic and magnetic properties as a function of x and a discontinuous, pos ...
IOP Publishing Ltd2023Momentum-Space Imaging of Ultra-Thin Electron Liquids in δ-Doped Silicon
Two-dimensional dopant layers (δ-layers) in semiconductors provide the high-mobility electron liquids (2DELs) needed for nanoscale quantum-electronic devices. Key parameters such as carrier densities, effective masses, and confinement thicknesses for 2DELs ...
WILEY2023Competition between Carrier Injection and Structural Distortions in Electron-Doped Perovskite Nickelate Thin Films
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jonathan Spring, Jean-Marc Triscone
The discovery of superconductivity in doped infinite-layer nickelate thin films has brought increased attention to the behavior of the doped perovskite phase. Despite this interest, the majority of existing studies pertain to hole-doped perovskite rare-ear ...
