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…
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…
Electrical properties of improper ferroelectrics from first principles
Massimiliano Stengel, Craig J. Fennie, Philippe Ghosez
We study the interplay of structural and polar distortions in hexagonal YMnO3 and short-period PbTiO3/SrTiO3 superlattices by means of first-principles calculations at constrained…
