“…[26][27][28][29][30][31] In the last few decades, PFM has allowed comprehensive studies on the processes of electrical polarization and wall dynamics of the ferroelectric domains, 32,33 switching of polarization and nucleation domains, 34,35 and the behavior of ferroelectric properties with different parameters in the preparation of materials. [36][37][38] Thus, in this context, this work is a thorough study of the structure of one-dimensional NaNbO 3 based on a set of experimental characterization techniques and an atomistic computational approach. In addition, the piezoresponse force microscopy tool was fundamental to measure the piezoelectric response of individual fibers, unveiling the relationship between the crystalline structure of the fibers and their piezoelectric behavior.…”
