“…Micromagnetic approaches [43] are based on the local resolution of Landau-Lifshitz-Gilbert equation of motion often in combination with finite element methods [44]. In order to account for magneto-elastic coupling, the elastic energy can be introduced with respect to the balance equations and the boundary conditions [45][46][47][48]. This point remains a complex issue particularly in the context of multiaxial stress.…”

“…To verify our hypothesis, numerical simulation based on phase field approach [30][31][32][33][34] has been carried out to simulate the evolution of nanomesa and nanowell pattern in P͑VDF-TrFE͒ films. The driving force of the evolution can be obtained from the variation of potential energy, and the rate of the evolution is assumed to be proportional to the driving force.…”

Self-organizing nanostructures are ubiquitous in both natural and synthetic materials. They are not only appealing scientifically, by revealing the intrinsic atomic and molecular interactions that might be difficult to detect otherwise, but may also hold the key for the development of novel functional structures and devices. For their technological potential to be fully realized, the size, morphology, and distribution of the self-organizing nanostructures must be regulated. In this paper, we investigate the principles under which the self-organizing nanostructures can be regulated via external mechanisms. Using nanomesa and nanowell formation in polyvinylidene fluoride trifluoroethylene copolymer film as an example, we demonstrate that the external mechanism, if appropriately applied, can not only change the structure stability and trigger pattern formation in the otherwise stable films where self-organizing nanostructure is impossible to form, but can also regulate the size, morphology, and distribution of self-organizing nanostructures in a very effective manner. While the analysis is carried out for a particular system, the principles should be applicable for a wide range of self-organizing materials and structures.
