Line Plot from Scientific Research

Profile of the piezoresponse across a BFO bundle extracted from the out-of-plane PFM amplitude image displayed in inset (between the two red arrows). The bright contrast observed on the BiFeO3particles corresponds to a polarisation pointing downward. The black contrast of the P(VDF-TrFE) matrix also corresponds to downward polarisation (P(VDF-TrFE) and BiFeO3have opposite signs for respective piezoresponse, leading to phase contrast inversion).
