Abstract |
We studied the fractal analysis in ferroelectric copolymer films to understand the effect of polarization relaxation on domain wall roughness. Under humidity-controlled conditions that can affect the polarization dynamics, polarization relaxation of irregular domains results from the domain back reversal at the boundaries where the antiparallel polarization encounters, and therefore has a significant influence on the fractal dimension of the irregular domains as a function of time. The polarization switching was characterized by piezoresponse force microscopy (PFM). The thickness was determined by transmission electron microscopy (TEM), and the crystalline structure was characterized by X-ray diffraction and Fourier transform infrared spectroscopy (FT-IR). |
