Interaction between point defects and vertical inversion domain walls in wurtzite AlN
Loris Naudin, Charles Paillard, Laurent Bellaiche +2
Alloyed aluminium nitride compounds constitute a promising class of ferroelectric materials due to their high remanent electric polarizations, large band gaps and structural compat…
Giant photostriction in lead-free ferroelectric stemming from photo-excited thermalized carriers
Gaëlle Vitali-Derrien, Oana Condurache, Antoine Ducournau +14
Ferroelectrics are polar materials whose polarization can be switched by applying electric fields; they offer unique opportunities to develop performant photostrictive materials, i…
Size-effects on shift-current in layered CuInPS
Francesco Delodovici, Brahim Dkhil, Charles Paillard
Two-dimensional ferroelectrics have recently emerged as a promising avenue for next-generation optoelectronic and photovoltaic devices. Due to the intrinsic absence of inversion sy…
Electro-optic effects in some sliding ferroelectrics
Xueqing Wan, Zhenlong Zhang, Charles Paillard +4
Sliding ferroelectrics, which exhibit out-of-plane polarization arising from specific stacking rather than conventional ionic displacements, are new types of ferroelectrics whose u…
Towards a deeper fundamental understanding of (Al,Sc)N ferroelectric nitrides
Peng Chen, Dawei Wang, Alejandro Mercado Tejerina +4
Density Functional Theory (DFT) calculations, within the virtual crystal alloy approximation, are performed, along with the development of a Landau-type model employing a symmetry-…
Photoinduced phase transitions and lattice deformation in 2D NbOX (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 (X = Cl, Br, I) using first-principles calculations. In particu…
