Figure 1: Giant electromechanical response in morphotropic La-doped BiFeO3 thin films.
From: Structural and electronic transformation pathways in morphotropic BiFeO3
(a) A schematic of the experimental geometry. (b) Spectroscopic local surface displacement as a function of applied external DC bias. (c) Same data as in (b), but without the initial quarter cycle. (d) A schematic illustration of the evolution of nanoscale phase transformations mediating the giant electromechanical response in BFO thin films.
