Time-resolved fractal dimension analysis in ferroelectric copolymer thin films using R-based image processing

We have developed time-resolved fractal dimension analysis in ferroelectric copolymer films in order to understand the effect of polarization relaxation on domain wall roughness. Interestingly, the progressive 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.
