Deformation-Potential-Driven Photostriction in Layered Ferroelectrics

S. Puri, R. Rodriguez, C. Dansou +5

The coupling between electronic excitations and lattice deformation in van der Waals ferroelectrics is governed by a competition between the electron deformation potential and the…

Photoinduced phase transitions and lattice deformation in 2D NbOX $_{2}$ (X=Cl, Br, I)

Carmel Dansou, Charles Paillard, Laurent Bellaiche

We present a comprehensive investigation of light-induced phase transitions and strain in two-dimensional NbOX $_{2}$ (X = Cl, Br, I) using first-principles calculations. In particu…

Tuning photostriction in (PbTiO $_{3}$ ) $_{n}$ /(SrTiO $_{3}$ ) $_{m}$ superlattices via chemical composition: An $ab-initio$ study

Carmel Dansou, Charles Paillard, Laurent Bellaiche

Light-induced mechanical deformations in single-domain (PbTiO $_{3}$ ) $_{n}$ /(SrTiO $_{3}$ ) $_{m}$ superlattices were simulated using first-principle calculations. By varying the chemi…

Tailoring photostriction via superlattices engineering

Carmel Dansou, Charles Paillard, Laurent Bellaiche

We report systematic first-principles investigation of light-induced mechanical deformations in monodomain (PbTiO $_{3}$ ) $_{n}$ /(SrTiO $_{3}$ ) $_{n}$ superlattices ( $n = 1 - 5$ ). We revea…
