摘要
Intrinsic charge transfer in mixed halide compounds PtX_(x)X'_(1-x ) was studied in the framework of the two-band extended Pielerls-Hubbard model.It was found that the number of transferred charges can be a fraction times of the electronic charge.The maximum amount of the transferred charges will occur at a certain proportion x for a given mixed compound.
