Curvature-Controlled Polarization in Adaptive Ferroelectric Membranes
Greta Segantini, Ludovica Tovaglieri, Chang Jae Roh +12
In this study, we explore the ferroelectric domain structure and mechanical properties of PbTiO-based membranes, which develops a well-ordered and crystallographic-oriented rip…
