Photostriction in two dimensional ferroelectrics

ORAL

Abstract

Within density-functional theory, we study light-induced structural deformations in two dimensional ferroelectrics due to their non-centrosymmetric nature. This effect, known as photostriction, was recently studied in bulk ferroelectrics [1]. [1] C. Paillard et al. \textit{Physical Review Letters}. 116(24):247401, 2016.
