| Abstract: | The physical properties of semiconductor-metal phase transition of the transition-metal complexes under low temperature have been studied by means of computer Monte Carlo simulation technique based on the multi-dimensional order parameter equation set obtained by the displacement transformation and ground state average in the Wannier representation. By implementing Monte Carlo self-consistent interaction quantum lattice simulation,the phase diagram of the system and the change relations between order parameters are gaind. |
