^{We performed two-dimensional model calculations to understand the operation of phase transition FETs using α-(BEDT-TTF)₂I₃, an organic strongly correlated material. We calculated the time evolution of charge densities at each independent site when an external static electric field in the conducting plane was applied. The influence of strong electric fields within the conducting plane caused changes in the transfer integrals, leading to the melting of the charge-ordered state and a transition of the charge density to the metallic phase.}
