Monte Carlo investigation of critical properties of ferroelectric films: The DIFFOUR Hamiltonian framework
In this work, Monte Carlo simulation was used to investigate the ferroelectric films behavior using the DIFFOUR Hamiltonian. The considered electric dipole directions were considered to range from 2 to 14 directions, in representing various domain structures. Metropolis algorithm was used to extract...
