A new method for the numerical modelling of physical phenomena described by nonlinear diffusion equations on a sphere is developed. The key point of the method is the splitting of the differential equation by coordinates that reduces the original 2D problem to a pair of 1D problems. Due to the splitting, while solving the 1D problems separately one from another we involve the procedure of map s...
We demonstrate an approach for probing nonlinear electromechanical responses in BiFeO(3) thin film nanocapacitors using half-harmonic band excitation piezoresponse force microscopy (PFM). Nonlinear PFM images of nanocapacitor arrays show clearly visible clusters of capacitors associated with variations of local leakage current through the BiFeO(3) film. Strain spectroscopy measurements and fini...
