Temperature-dependent classical phonons from efficient non-dynamical simulations
Mathias P. Ljungberg, Jorge Íñiguez
We present a rigorous and efficient approach to the calculation of classical lattice-dynamical quantities from simulations that do not require an explicit solution of the time evol…
Domain walls in a perovskite oxide with two primary structural order parameters: first-principles study of BiFeO
Oswaldo Diéguez, Pablo Aguado-Puente, Javier Junquera +1
We present a first-principles study of ferroelectric domain walls (FE-DWs) in multiferroic BiFeO (BFO), a material in which the FE order parameter coexists with anti-ferrodisto…
High mobility conduction at (110) and (111) LaAlO3/SrTiO3 interfaces
Gervasi Herranz, Florencio Sánchez, Nico Dix +2
In recent years, striking discoveries have revealed that two-dimensional electron liquids (2DEL) confined at the interface between oxide band-insulators can be engineered to displa…
One-dimensional half-metallic interfaces of two-dimensional honeycomb insulators
N. C. Bristowe, Massimiliano Stengel, P. B. Littlewood +2
We study zigzag interfaces between insulating compounds that are isostructural to graphene, specifically II-VI, III-V and IV-IV two-dimensional (2D) honeycomb insulators. We show t…
Epitaxy-distorted spin-orbit Mott insulator in Sr2IrO4 thin films
C. Rayan Serrao, Jian Liu, J. T. Heron +14
High quality epitaxial thin films of Jeff=1/2 Mott insulator Sr2IrO4 with increasing in-plane tensile strain have been grown on top of SrTiO3(001) substrates. Increasing the in-pla…
Ferroelectricity in ultrathin film capacitors
Céline Lichtensteiger, Pavlo Zubko, Massimiliano Stengel +4
Going down to the limit of ultrathin films holds promise for a new generation of devices such as ferroelectric tunnel junctions or resistive memories. However, these length scales…
