Polar meron-antimeron networks in strained and twisted bilayers
Daniel Bennett, Gaurav Chaudhary, Robert-Jan Slager +2
Out-of-plane polar domain structures have recently been discovered in strained and twisted bilayers of inversion symmetry broken systems such as hexagonal boron nitride. Here we sh…
Tunable photostriction of halide perovskites through energy dependent photoexcitation
Bo Peng, Daniel Bennett, Ivona Bravić +1
Halide perovskites exhibit giant photostriction, that is, volume or shape changes upon illumination. However, the microscopic origin of this phenomenon remains unclear and there ar…
Coupling between tilts and charge carriers at polar-nonpolar perovskite interfaces
Daniel Bennett, Pablo Aguado-Puente, Emilio Artacho +1
The phenomenological theory for the polar instability giving rise to a two-dimensional electron gas at perovskite interfaces is hereby extended to include the coupling to perovskit…
Generalized relation between electromechanical responses at fixed voltage and fixed electric field
Daniel Bennett, Daniel Tanner, Philippe Ghosez +2
We present a general relation between the electromechanical couplings of infinitesimal strain and electric field to arbitrary order, measured at fixed voltage and at fixed electric…
