Dielectric Property of a Large‐Scale Transferred Single‐Crystal BaTiO3 Film Prepared Using a Water‐Soluble Sacrificial Buffering Layer

open access: yesAdvanced Materials Interfaces, EarlyView.
A large‐scale single‐crystal BaTiO3 thin film is successfully transferred to a PET substrate using Ba‐doped Sr3Al2O6 water‐soluble sacrificial layer, which reduces the mismatch strain between the objective film and the substrate. The high crystallinity of BaTiO3 is maintained during the transfer process, and a very low dielectric loss (tanδ < 0.1) of ...
