Impurity-Induced Interchain Coupling in Quasi-One-Dimensional Halogen-Bridged Platinum Complex (HMPC)

Based on the experimental data, a model Hamiltonian which is appropriate to describe doped quasi-one-dimensional halogen-bridged mixed-valence platinum complexes(HMPC's)was presented. Using Geen's function, the binding energy of polaron, which is a defect state by doping-induced, as a function of impurity concentration was calculated numerically. The conductivity mechanism in HMPC was discussed detail, it could explain the change of conductivity caused by doping.
