Abstract: The external force induced phase transition properties of a honeycomb-structured ferroelectric thin film described by a spin-12 transverse Ising model were investigated by use of the effective field theory with correlations (EFT). The forces were introduced into the systems by performing three different interaction functions. The results demonstrate that characteristic phase diagrams and phase regions are strongly dependent on the added external force. In particular, the whole process of phase transition from ferroelectric to paraelectric and then back to ferroelectric was revealed in a 3-D (dimensional) phase diagram vividly for the first time suggesting that forces can be used to control pseudo-spin polarizations in the hexagonal lattice sensitively.
