Light-Induced Transient Polarization Reversal in Rhombohedrally Stacked Bilayer Transition Metal Dichalcogenides via an Electronic Mechanism
Xiangzhou Zhu · Stefano Mocatti · Matteo Calandra
Abstract
Author(s): Xiangzhou Zhu, Stefano Mocatti, and Matteo Calandra<br/><p>Light-induced sliding ferroelectricity in two-dimensional van der Waals materials enables polarization control via relative layer motion. However, polarization switching occurs on the timescale of shear modes (tens of picoseconds) and requires very large fluences, potentially damaging the samples. H…</p><br/>[Phys. Rev.
