Abstract
Polarons and bipolarons in mixed halide MX compounds were studied in the fr
ame work of the two-band extended Peierls-Hubbard model. Different from the
isolated MX chains,it was found that the segments tend to select impuritie
s in mixed halide compounds. Then the charge confinement and the effect of
electron-electron interactions were investigated. Finally the properties of
impurities in mixed halide compounds with spontaneous charge transfer were
also discussed.
