Structural instabilities of infinite-layer nickelates from first-principles simulations
Álvaro Adrián Carrasco Álvarez, Sébastien Petit, Lucia Iglesias +3
Rare-earth nickelates RNiO adopting an infinite-layer phase show superconductivity once La, Pr or Nd are substituted by a divalent cation. Either in the pristine or doped form,…
First-principles study of electron and hole doping in perovskite nickelates
Lucia Iglesias, Manuel Bibes, Julien Varignon
Rare-earth nickelates RNiO (R=Lu-Pr, Y) show a striking metal-insulator transition in their bulk phase whose temperature can be tuned by the rare-earth radius. Th…
Tuning oxygen vacancy diffusion through strain in SrTiO thin films
Lucía Iglesias, Andrés Gómez, Martí Gich +1
Understanding the diffusion of oxygen vacancies in oxides under different external stimuli is crucial for the design of ion-based electronic devices, improve catalytic performance,…
Epitaxial stabilization of pulsed laser deposited SrIrO thin films: entangled effect of growth dynamics and strain
A. Gutiérrez-Llorente, L. Iglesias, B. Rodríguez-González +1
The subtle balance of electronic correlations, crystal field splitting and spin--orbit coupling in layered Ir oxides can give rise to novel electronic and magnetic phases. E…
Oxygen vacancies in strained SrTiO thin films: formation enthalpy and manipulation
L. Iglesias, A. Sarantopoulos, C. Magen +1
We report the enthalpy of oxygen vacancy formation in thin films of electron-doped SrTiO, under different degrees of epitaxial stress. We demonstrate that both compressive an…
