Theory of PbTiO3, BaTiO3, and SrTiO3 Surfaces
First-principles total-energy calculations are carried out for (001) surfaces of the cubic perovskite ATiO3 compounds PbTiO3, BaTiO3, and SrTiO3. Both AO-terminated and TiO2-terminated surfaces are considered, and fully-relaxed atomic configurations are ...

Artificial ferroelectric materials
Dans ce travail, nous étudions les propriétés de superréseaux de PbTiO3 et SrTiO3. Pour des couches épaisses de chacun des constituants, le système se comporte comme prévu par notre modèle électrostatique, en trouvant un équilibre entre les propriétés ferro- et paraélectrique de ces derniers.

Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Ferroelectric Materials: A Novel Pathway for Efficient Solar Water Splitting
Over the past few decades, solar water splitting has evolved into one of the most promising techniques for harvesting hydrogen using solar energy. Despite the high potential of this process for hydrogen production, many research groups have encountered ...

It is shown that interfaces between organic and inorganic layers govern long‐range stacking disorder and in‐plane anisotropy in 2D metal‐halide perovskites. By comparing single‐cation AB‐AB and ordered mixed‐cation ABCD‐ABCD stackings, SCXRD reveals enhanced mosaicity, while optics confirm high birefringence.

In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.
