Factors Influencing Ferroelectric Switching Behavior in Perovskite Nanofibers

Given the complexity in probing ferroelectricity on the nanoscale, piezo force microscopy observations have often become defacto proof of ferroelectric behavior, without considering the factors influencing the signal origination. In this work, limitations in using existing ferroelectric characterization for nanofibers are discussed. Decreasing piezo-response and shrinking hysteresis loops with increasing relative humidity were observed which could be attributed to tip-surface mechanics influenced by the testing environment.
